Amplifier output signal monitor.
Each monitor can output either the
entered signal immediately before
A/D converter or the signal after
switching between 2 types of input
signals. The 2 types of input signals
can be selected by the control
register and output.
These pins are emitter follower
outputs, but the internal bias current
is so small that a 820Ω resistor
should be connected between these
pins and GND to monitor high
frequency signals.
When not used, connect to AVCCAMP.
Power supply for amplifier block.

Sync separated SYNC signal output.
Separates and outputs the SYNC
signal from SYNC ON GREEN input
signal.
(SYNC signal input from SYNCIN1
and SYNCIN2 pins can be output.)
Both positive and negative polarity
outputs are supported.
The polarity is selected by the control
register.
SYNC ON GREEN signal inputs.
Input via a 0.1µF capacitor.
When not used, connect to AVCC.
The SYNC TIP clamp level is
approximately 2.0V + Vf (0.8V) =
approximately 2.8V. At this time, if
the pin voltage is lowered, these pins
go to low impedance and current
flows from the IC.
When these pins are at the SYNC
TIP level or higher, the clamp circuit
is off and only an input base current
of approximately 1.2µA flows.

2) Threshold voltage
In I2C bus mode, both SDA (Pin 9) and SCL (Pin 10) are input. These input logic signals can have two
threshold voltages by the 3-wire/I2C.
These threshold voltages have the following hysteresis.

3-wire Bus Mode
Various control can be performed by setting the internal control register values via the serial interface
comprised of the three pins SDA (Pin 9), SCL (Pin 10) and XSENABLE (Pin 11).
Data can be accepted when XSENABLE is low level. When XSENABLE is high level, data cannot be
accepted. The SDA pins of multiple IC can also be connected to the same bus line and each IC can be
controlled independently by XSENABLE.
XSENABLE may change the state when SCL is high level.
1) Write mode
8-bit control data consisting of a 7-bit sub address and 1-bit READ/WRITE setting is input in series from the
LSB to the SDA pin. When READ/WRITE setting is "1", data can be written to register. When this IC is used
in 3-wire bus mode, the sub address is 5 bits, so always set the 2 MSB bits to "0".
Input the clock to the SCL pin. Data is loaded to the SDA pin at the rising edge of this clock. The data is set
in the register at the rising edge of XSENABLE.
The SDA and SCL pins are also used in I2C bus control mode.

2) Read mode
Input the 7-bit sub address and 1-bit READ/WRITE setting to the SDA pin.
When READ/WRITE setting is "0", the 8-bit internally set data is output in series from the LSB by the
SEROUT (Pin 12). While data is being output from the SEROUT pin, don't care what data is input to the
SDA pin.
Use the read function to check whether the data is set correctly inside the IC.

Power-on Reset
When the power supply rises, the power-on reset circuit operates and all the control register data is set to "1".
AMP, ADC, PLL and SYNCSEP are all set to power save mode, and all the TTL output pins are set to high
impedance mode. Therefore, it is possible to share the same bus interface with other digital outputs having
high impedance modes.

I2C BUS Mode
Various control can be performed by setting the internal control register values via the serial interface
comprised of the SDA (Pin 9) and SCL (Pin 10). This mode has only a write mode for setting data, and there
is no read mode. Therefore, address "S0" set READ/WRITE is always "0".

The pin threshold voltages are set to 1/4VCC, 1/2VCC and 3/4VCC.
An 8-bit slave address (IC address), 8-bit sub address, and a number of 8-bit data strings are input in series
from the MSB to the SDA pin. When this IC is used in I2C bus mode, sub address is 5 bits, and 3 bits of MSB
side are set to always "0". ACK signal is returned from the IC to confirm that the data has been received for
each 8-bit data.
The sub address can be designated optionally. The sub address is auto-incremented in order from the
designated sub address, and the data strings are loaded in succession.
To set the data at a specific separated sub address, either send the stop condition and then reset the sub
address, or also send the data of unchanged portions so that the data is continuous. Only auto-increment
mode is supported, and the sub address + data + sub address + data mode where only specific sub addresses
are designated is not supported.

Amplifier
This is a 3-channel AMP that optimizes the AC coupled RGB analog input signals and YCbCr analog input
signals for ADC input. Switch input mode between RGB input or YCbCr input with the control register. The
AC coupled analog input signals are synchronously clamped by the externally input clamp pulse at a
pedestal level. An input capacitor of 0.1µF is recommended.
Allowing two lines of input to be selected for the analog input signal, the AMP includes a high frequency, low
cross talk video switch circuit for input switching. Switching is performed using a control register. When using
only one line, leave the unused line open.
The input band of the analog input signal is 220MHz in the –3dB bandwidth range.
There are main contrast and sub-contrast of the gain used to adjust the analog input signal to full scale (1V
typ.) of the ADC. Each can be adjusted to one of 256 levels using control registers. Main contrast is
controlled by moving the gain of the 3 RGB channels. The each gain of the 3 RGB channels can be
controlled independently.
In RGB input mode, the clamp level used for the black level adjustment can be adjusted independently for
the 3 channels to any of 256 levels by using sub-brightness.
The ∗CLP pin∗1 is connected to the hold capacitor of the clamp circuit for the sub-brightness. A hold capacitor
of 0.1µF is recommended.
The ∗OUT pins∗2 can output signal immediately before input to the ADC or the signal after switching between
the two lines of input select switch. Either of them can be selected by control register. As for emitter follower
output, since the internal bias current is small, be sure to connect an 820Ω resistor between the ∗OUT pins∗2
and AGND in order to view the signal with a high frequency. A 75Ω driver cannot be supported. In addition,
load capacitance should be 5pF or less.
When the SYNC ON GREEN signal is monitored at the ∗OUT pins∗2 after the two lines of select switch, the
sync amplitude is a maximum of 0.3V, for a limiter is applied at the amplifier input stage.
In YCbCr signal input mode, Y can be adjusted to any of 256 levels using the sub-brightness while Cb and Cr
can be adjusted to any of 64 levels using the Cb or Cr offset.
A detailed description of the above registers is given below.
∗1 ∗CLP pins: Overall naming for R/Cr CLP (Pin 130), G/Y CLP (Pin 128), B/Cb CLP (Pin 129)

• Analog input signal mode switching
Analog input signal supports both RGB analog input signal and YCbCr analog input signal.

• Brightness clamp off function
Clamp operation can be set to a mode where only the post-stage brightness clamp does not operate even if
a clamp pulse is input to the CLPIN (Pin 113). At this time, all three channels of the ∗CLP pins∗1 are set to
high impedance simultaneously, and the signal black level can be varied in an analog manner by setting the
voltages externally. However, the voltage value set here is not related to the VRT (Pin 17) and VRB (Pin
93) voltages or the ∗OUT∗2 monitor signal output DC levels. Therefore the value should be set while

CXA3506R
SYNCSEP
The SYNCSEP function can be used to separate and output the SYNC signal that is superimposed on the
SYNC ON GREEN signal (including the SYNC ON Y signal).
There are two major SYNCSEP circuits. One is the circuit for creating a SYNC signal to be input to the PLL,
and the other is a circuit for outputting a SYNC signal from the SOGOUT (Pin 105) so that a clamp pulse can
be created externally. These SYNCSEP circuits perform processing on entirely different channels.
(See the block diagram for the SYNCSEP operational description.)
• SYNCSEP circuit for the PLL SYNC signal
In the case of the SYNC ON GREEN signal, the SYNC ON GREEN signal is AC coupled to the G/YIN1 (Pin
124) or the G/YIN2 (Pin 126) and the sync component is separated and used as a reference. An input
capacitor of 0.1µF is recommended.
When a signal is input to this pin, the pedestal level is clamped by a clamp pulse input to the CLPIN (Pin
113). After this, the signal is split into a signal to the amplifier circuit and the signal to the SYNCSEP
circuits, and the SYNC signal is sent through a two lines of input select switch (SW SOGP) and the SYNC
signal is separated by the SYNCSEP circuits. At this time, it is possible to minimize the jitter of the SYNC
signal sent to the PLL by using a control register to select the threshold level (VTH) and hysteresis level
(VHYS) of the SYNCSEP circuit according to the type of noise on the superimposed SYNC signal.

• SYNCSEP circuits for the SYNC signal for the clamp pulse
A SYNC ON GREEN signal is input to the SOGIN1 (Pin 132) or SOGIN2 (Pin 135). The AC coupled signal
is internally sync tip clamped and the minimum level (bottom of sync) is turned into the internally-set DC
level (approximately 2.8V).
The sync tip clamped input signal is separated from the threshold of 165mV (at SYNC DUTY 5%) above
from the bottom of the sync by the SYNCSEP circuit. After this, the signal is output at TTL level from the
SOGOUT pin and used as a reference signal for generating a clamp pulse.
Since no clamp pulse is required for the sync tip clamp, it is possible to output a SYNC signal from the
SOGOUT pin even when there is no external clamp pulse present such as when power supply is turned on.
An input capacitor of 0.1µF is recommended.
A control register can be used to select output either the SYNC signal separated out from the signal input
from the SOGIN1 pin or the SOGIN2 pin by SW SOG O or the previously described PLL SYNC signal
output from the SW PLL circuit.

When SYNC is positive polarity, set SYNC POL to "1". (Clock is generated in sync with the rising edge of
SYNC.)
When SYNC is negative polarity, set SYNC POL to "0". (Clock is generated in sync with the falling edge of
SYNC.)
When there is no SYNC input, the VCO oscillates at random and a random pulse is output from the CLK output.

• Phase detector (PD)
The phase detector compares the phase of the SYNC signal with that of the programmable counter output
signal. The phase comparison is performed at the edge, and a phase difference between the compared
signals is output as a pulse.
There is no hysteresis function for the input pins of the SYNC signal (SYNCIN1 and SYNCIN2) input to the
phase detector. If necessary external waveform shaping should be done as jitter results when a noisy signal
is input. Set the control register, PD POL, to "1" as for the input polarity of the phase detector.
• Hold function
The hold function holds the VCO input voltage and generates oscillation itself without performing phase
comparison. The VCO oscillation frequency is held during this period without performing phase comparison,
by inputting the HOLD signal from the HOLD (Pin 106).
HOLD signal polarity can be set by using the control register: HOLD POL.

• Charge pump (CP)
The charge pump sets charge pump current to flow for the amount of time corresponding to the pulse width
output from the phase detector. The phase detector gain is determined by the charge pump current.
The amount of current can be varied by using a control register.
This IC is used to set the charge pump current value according to the VCO oscillation frequency as given

• Loop filter (LPF)
The control voltage input to the VCO is the pulse current output from the charge pump circuit that is
smoothed by an integrating circuit (loop filter). The resistor and capacitor values of the integrating circuit are
as follows. (For the circuit configuration, see the application circuit.)
C1 = 0.33µF
C2 = 330pF
R1 = 3.3kΩ
For the resistor and capacitors, use a metal film chip resistor with little temperature variation and ceramic
chip capacitors. In particular, the 0.33µF capacitor should be equivalent to high dielectric constant series
capacitor type B or better.
(Electrostatic capacitance change ratio ±10%: T = –25 to +85°C)
In case of using any resistors or capacitors except those given above, it is not guaranteed.

• VCO frequency dividers (DIV 1, 2, 4, 8)
The oscillation frequency of the VCO can be divided to 1/1, 1/2, 1/4, or 1/8 according to a control register setting.
Depending on the combination of the VCO oscillation frequency and VCO frequency divider, the Point B
clock frequency covers an operating range of 5MHz to 120MHz. The matrix of the VCO frequency divider
setting is as follows.

• Programmable counter
The clock frequency at Point B is divided and a programmable counter output signal is generated.
The frequency division ratio can be set optionally by using a 12-bit control register. This is determined by
using lower order 3 bits and upper order 9 bits in the following formula.
Frequency division ratio = (m + 1) × 8 + n
m: 9 bits (VCO DIV Bit 3 to 11)
n: 3 bits (VCO DIV Bit 0 to 2)

• Clock output
When the input polarity of the SYNC signal is positive, the clock output is synchronized to the rising edge of
the SYNC signal and is available as complementary signals CLK (Pin 99) and XCLK (Pin 98). The delay
time of the clock output can be varied in the range of 1/32CLK to 64/32CLK by using a control register (see
PLL timing diagram). Although the clock output can be turned off independently by using a control register,
it cannot be set to high impedance. The operational frequency of the clock is up to 100MHz.

• 1/2 clock output
1/2 clock signal is a signal that resets the clock by using a reset pulse created from an internal delay sync
signal and divides the clock in half. The complementary signal is output from the 1/2CLK (Pin 101) and
1/2XCLK (Pin 100). (See the PLL timing diagram). Although the 1/2 clock output can also be independently

• Delay sync output
Two types of delay sync signal (DSYNC and DIVOUT) can be output from the DSYNC/DIVOUT (Pin 103).
This is selected by switching a control register. The DSYNC signal is output as the input SYNC signal
undergone timing control. The DIVOUT signal is output as the programmable counter output undergone
timing control.
Both can be used as reset signals for any connected IC such as a scaling IC.

A SYNC signal input that has been timing controlled by a clock generated by a PLL is output.
Although only the forward edge is completely managed at this time with delay settings, etc., the back
edge has an undefined width for one clock cycle because it latches and outputs the input SYNC signal.
• DIVOUT signal
A timing controlled programmable counter output signal is output. In addition to the COARSE DELAY
that has been set by using the DSYNC signal, the delay time setting is output with a delay of 4 or 5
clocks. The pulse width is also managed by a clock.

Notes on Using the HOLD Signal and XTLOAD Signal (Reset Signal)
If the cycle of the SYNC signal is lost, the phase difference between the SYNC signal and the programmable
counter output in the phase detector will increase, and it will cause PLL unlock. At this time, the HOLD signal is
input to the HOLD (Pin 106), phase comparison is stopped while the signal is high level (when the HOLD POL
register is set to "1"), and the clock can be stably oscillated by holding the VCO oscillation frequency. Note,
however, the correspondence differs depending on whether the number of locations where the SYNC signal
period changes (the 0.5H region in the diagram) is odd or even.

When the number of the 0.5H period is odd, if only the HOLD signal is used, the phase difference between the
SYNC signal and the programmable counter output signal will increase in the extra 0.5H region and the lock
will be lost momentarily.
In this case, the 0.5H region is held by the HOLD signal, and it is possible to use the XTLOAD signal (reset
signal) at 1H backward to the official counter period by resetting/setting the counter value.
Although there are no particular restrictions on the setup time and hold time of the XTLOAD signal (reset
signal), the pulse width of the XTLOAD signal (reset signal) is restricted while the HOLD signal is high. (When
the HOLD POL register is set to "1".)
If the rising edge of the XTLOAD signal (reset signal) is delayed by 8CLK from the falling edge of the SYNC
signal, counter output will be obtained by synchronizing with the falling edge of the next SYNC signal. See the
diagram for details on timing.

• UNLOCK timing
If the phase difference between the SYNC signal input and the programmable counter output signal to the
phase detector (PD) increases, it becomes impossible for the VCO to maintain stable oscillation. This status is
converted into the UNLOCK signal and output. It is possible to perform analog lock/unlock by connecting an
external circuit to this pin.

The UNLOCK output is an open collector. By connecting the external circuit shown above to this output pin, it

R1, R2 and C1 above are reference values. The resistor R3 should be 50kΩ and Q1 should be 2SC series.

Case 2: When there is a phase difference, the S1 signal will goes low and high as shown in the figure below.
At this time, the falling edge slew rate of the S2 signal is determined by the current I1 flowing into this
open collector. The falling edge slew rate of the S2 signal will therefore be delayed as resistor R1
increases. In addition, since the rising edge slew rate of the S2 signal is determined by the current I2,
the rising edge slew rate of the S2 signal will become faster as the resistor R2 decreases. If the
integrated S2 signal does not fall below the threshold level of the next inverter, the UNLOCK signal
will remain low. This will therefore be judged as locked even if there is a phase difference.

the S2 signal will become slower. If the integrated S2 signal is under the threshold level of the next

The CXA3506R's charge pump is a constant-current output type as shown below.
When a constant-current output charge pump circuit is used inside the PLL,
the phase detector (PD) output acts as a current source, and the dimension of
its transmittance KPD is A/rad. Also, when considering the VCO input as a
voltage, the LPF transmittance dimension must be expressed in ohms (Ω =
V/A).
Therefore, the PLL transmittance when a constant-current output charge
pump circuit is used is as follows.

The loop filter F(S) is described below.
The loop filter smoothes the output pulse from the phase detector (PD) and inputs it as the DC component to
the VCO. In addition to this, however, the loop filter also functions as an important element in determining the
PLL response characteristics.
Typical examples of loop filters include lag filters, lag-lead filters, active filters, etc. However, the CXA3506R's
LPF is a current input type active filter as shown below, so the following calculations show an actual example
of deriving the PLL closed loop transmittance when using this type of filter and then using this transmittance to
create a formula for setting the filter constants.

This is the PLL transient response characteristic, and serves as a measure of the PLL stability. It is
determined by the loop gain and the loop filter.
A capacitor C2 is added to the actual loop filter.
This added capacitor C2 is used to reduce the R noise, and a value of around 1/10 to 1/1000 of C1 should be

CLK Jitter Evaluation Method
The generated CLK is obtained by inputting Hsync to the CXA3506R. Apply this CLK to a digital oscilloscope
and observe the CLK waveform using Hsync as the trigger.

Tj p-p
The CLK jitter is measured at peak to peak in the long-term write mode of the digital oscilloscope as shown in
the figure. The CLK jitter size varies according to the difference in the relative position with respect to Hsync.
Therefore, when the observation point is changed, the CLK jitter at that point is observed.
Jitter amount Tj p-p
The figure below shows a typical example of the CLK jitter for the CXA3506R.
The CLK jitter increases slightly at the rising edge of Hsync (in the case of positive polarity), and then settles
down thereafter. However, this is not a problem as the active pixels start after about 20% of the H cycle has
passed from the rising edge of Hsync.

• Analog input signal
The RGB analog input signal and YCbCr analog input signal are converted to digital signals and output. Be
sure to adjust the input dynamic range of the ADC in the pre-stage amplifier block by performing contrast and
brightness settings for the analog signal input to the ADC. (See the item on the amplifier for details on the
setting procedure.)
• Sampling clock
Although the sampling clock is created by a PLL (internal CLK), it is also possible to externally input a clock
to the ADC (external CLK) directly for checking ADC operations. In this case, be sure to make the register
settings below in order to input a PECL level clock from the CLKIN (Pin 110) and the XCLKIN (Pin 109).
Register: VCO By-pass

ADC clock
External CLK
Internal CLK
Note, however, that even if an external CLK is input under the above settings, it is impossible to run the ADC
at the input clock frequency unless the PLL's VCO frequency divider is set to 1/1. Running the ADC on an
external CLK is done in order to check the operations of the ADC. Normally, it should be run on the internal
CLK generated by the PLL.
• Reference voltage
The input dynamic range of the ADC is determined based on the reference voltage from the VRT (Pin 17)
and the VRB (Pin 93). Since this reference voltage is created using an internal band gap voltage, there is no
need for an external reference voltage circuit. The voltage at the VRT pin is set to a voltage approximately
0.4V lower than the voltage coming from the AVCCAD3 power pin. Also, the VRB pin is set to a voltage
approximately 1.0V lower than that at the VRT pin.
Capacitors of 1µF or more should be connected between the AVCCAD3 power supply pins for these
reference voltage pins (VRT pin and VRB pin).
If the value of the capacitor is too low or no capacitor is attached, the reference voltage circuit will cause an
oscillation that results in noise or malfunction because the ADC faithfully samples this oscillation.
It is impossible to apply an external voltage to a reference voltage pin. Note that it is also impossible to use
the voltage generated by a reference voltage pin as an external voltage source.
• Operational mode
The ADC output data of this IC supports five types of operational mode. Each operational mode is set by
using a control register.

• Description of the operational modes
(Straight Data out Mode)
An RGB analog input signal AC coupled is optimized by using a 3-ch AMP and the signal is input to the ADC.
The analog input signal input to the ADC is sampled by using a clock generated by the PLL.
The identical signal with the sampling clock for analog input signal is output from the CLK (Pin 99).
The sampled analog input signal is output from the port A side of the data output with a 3-clock pipeline
delay. Note that output for port B side is turned off at this time and cannot be set to high impedance.
The ADC data output is output with a propagation delay (Td_8) ranges from 2.2ns (min.) to 3.8ns (max.)
versus the clock output from the CLK pin.
The operational frequency in Straight Data out Mode is 100MHz at the sampling clock frequency.
Also, note, when operating in Straight Data out Mode, that the output on the port B side (RB0 to RB7, GB0 to
GB7, and BB0 to BB7) is turned off and cannot be set to high impedance.
All TTL output are set to high impedance only when this IC is put into power save mode.

• EVEN/ODD function
When a toggle signal created by dividing the Vsync signal in half is input to the EVEN/ODD (Pin 108), the
ADC sampling clock is inverted every Vsync signal.
This function can be used to configure a single frame screen from two fields by AD converting an RGB
analog input signal that requires high speed and high resolution, such as a UXGA 60Hz (162MHz) or more
signal, at half the frequency of the original ADC sampling rate.
There are no particular control register settings when using the EVEN/ODD function. The sampling clock is
inverted based on the polarity of the signal input to the EVEN/ODD pin. Be sure to input signal to the
EVEN/ODD pin at TTL level.

TTL Output Mode during Power Save Mode
All TTL output pins are set to high impedance when the IC is put into power save mode.
Since this IC supports power on reset, AMP, ADC, PLL, and SYNCSEP are set to power save mode when
power is turned on and all TTL output pins are set to high impedance.
However, note that the TTL output pins don't change into high impedance, when control register are used to
set each TTL output disable mode separately. Even though there are also modes in which data output ports
are set to output off mode based on the ADC operational mode, it cannot be set to high impedance.

Notes on Operation
• On the PC board, prepare a solid ground pattern having as large an area as possible, and placing the IC in
the center, divide this area into an analog region and digital region.
• The loop filter area of the PLL block plays an important role in terms of performance. It is therefore located as
close as possible to the IC pins and the periphery is guarded with AGND. Also, be sure to use capacitors and
resistors for the loop filter that should be temperature compensated and do not change the values.
• Be sure to use a metal film resistor for the resistor connected to IREF (Pin 121).
• The wiring for SYNCIN1 (Pin 111) and SYNCIN2 (Pin 112) should be as short as possible and each needs to
be shielded by ground.
• Use a 0.1µF ceramic chip capacitor for the bypass capacitor attached between the power supply and ground.
The capacitor should be attached to the pin as close as possible.
• Use a 1µF ceramic chip capacitor for the capacitor attached to the VRT (Pin 17) and the VRB (Pin 93) and
connect to the AVCCAD3 (Pin 16 and Pin 94) as close as possible.
• Equalize and shorten the lines of RGB analog input signals, if possible. Each line needs to be shielded by
ground. (This is the same for the R/CrCLP, G/YCLP, and B/CbCLP pins.)
• A 0.1µF capacitor is recommended for attachment to the RGB analog input pins. The less the capacitance
becomes, the more the sag by leak current becomes. The more the capacitance becomes, the more start up
time takes in case of putting power source into the IC. (This is the same for the R/CrCLP, G/YCLP, and
B/CbCLP pins.)
• Design boards so that the wiring for the R/CrIN, G/YIN, and B/CbIN and R/CrOUT, G/YOUT, B/CbOUT pins
is as separated as possible.
• Use a pattern width that takes characteristic impedance into account for signal wires terminated at 75Ω.
• There are no particular restrictions on the power-on sequence.
• Although there are AVCCAD3 and DVCCAD3 as 3.3V power supply, use the same 3.3V analog power supply
to each on the board.
• AGNDAD3 and DGNDAD3 are the ground for AVCCAD3 and DVCCAD3, respectively. Use the same ground
for AGNDAD3 and DGNDAD3. Although AGND is the ground recommended for AGNDAD3 and DGNDAD3,
there are no problems in terms of operation even if connected to DGND. (The special evaluation board in the
Application Circuit is connected to DGND.)
• Although 5V power supply is divided into both analog and digital power supply lines, be sure to wire boards
so that no potential difference arises between these power supplies.
• Load capacitance of the data output wires causes the change for the worse of slew rate and noise. Be sure
to use short layouts with the finest wires possible.
• Put this IC into power save mode when making a connection between data output and another IC. (High
impedance cannot be set when pins are disabled separately.)

CXA3506R Evaluation Board
Overview
The CXA3506R Evaluation Board is a special board designed for the easy evaluation of the CXA3506R
developed for the LCD projector and monitor so that performance can be maximized. The DSUB 15-pin
connector is used as the input connector that allows the direct input of a video signal from a PC. The input
video signal is A/D converted by the CXA3506R and a pin for monitoring is designed onto the board so that
output data can be checked directly.
The 10-bit high speed D/A converters are built onto the board so that the performance of the IC can be easily
checked. Picture quality can be easily evaluated by using a CRT monitor since the D/A-converted video signal
is output from the DSUB 15-pin connector for output in addition to the DSYNC output of the CXA3506R.
Features
• Single +5V power supply (with built-in 3.3V regulator)
• Allows two-line video signal input
• Data output port is also used as output data monitoring pin
• CXA3506R output is D/A converted and is easily monitored by a CRT
• Supports 2 types of control registers (3-wire and I2C)
Operating Conditions
• Supply voltage: +5V (typ.)
• Current consumption: 830mA (typ.)
• Input signal: Separated sync video signal

Using the CXA3506R Evaluation Board
The CXA3506R Evaluation Board can be used to easily evaluate just by connecting a power supply, video
signals, and control register signals.
The procedure is described below.
1. Connect the power supply to the power connection pin. (GND/+5V)
Do not apply power supply in this state.
2. Check the direction of SW1.
SW1 is the power save control switch. The CXA3506R is put into power save mode when SW1 is set to the
rear position (↑). Set SW1 to the forward (↓) position when using the CXA3506R.
SW1 is connected to the XPOWER SAVE pin.
3. Connect the special control register signal cable.
Connect the cable to CON4 when using I2C control. Set SW2 and SW3 to the forward (↓) position. While,
connect the cable to CON5 when using 3-wire control. Set SW2 and SW3 to the rear (↑) position.
In addition, check that the short pin (I2C) is in the "00" position in case of using I2C control.
4. Input the RGB analog signals from the CON1 pin (Video In 1).
XGA60 is recommended as the initial signal because the control program default value is set for the XGA60.
XGA60: Vsync 60Hz
Hsync: Video signal for 48kHz
N = 1344
5. The RGB analog signal for simple picture quality evaluations is output from the CON3 pin (Video Out).
Be sure to connect the CON3 pin to a CRT monitor that can process a signal of XGA60 or more.
6. Turn on the power.
Check a current to be about 360mA flows through the 5V power supply.
If there is much more current than this, immediately turn off the power and check that there are no
misconnections.
7. Run the control program.
Click on "re-load" at the bottom right of the control program screen, and check a current to be about 830mA
flows through the 5V power supply.
If everything works normally, an processed image for picture quality evaluation appears on the CRT
monitor.
Reconfirm the above items from the beginning if the processed image does not appear.

CXA3506R
Notes on Using CXA3506R EVB
1. RGB analog signals input from CON1 or CON2 are A/D converted.
The digital signals are D/A converted.
In addition, the analog signals are output in AC coupling.
Therefore, the output are the RGB analog signals output from CON3.
In this reason, when the RGB analog signals output from CON3 undergo picture quality evaluation by using
a CRT monitor, note that on-screen evaluation cannot be confirmed about the functions of SUB
BRIGHTNESS and Cb/Cr OFFSET. This is due to the fact that the DC component disappears because the
RGB analog signals are output in AC coupled after output by the D/A converter, even if the DC offset is
changed.
2. The current consumption for this board immediately after turning on the board's power is approximately
360mA. Board current is 830mA when the CXA3506R control register is started after this.
When turning on power to the board, be sure to check the board current and make sure that connections
are correct.
3. Although this board is equipped with a –5V power supply pin, it can operate by using a single 0/+5V power
supply.
Be sure to leave the –5V power supply pin open.
Notes Regarding the Control Program
1. When the program is accurately installed on the PC, be sure to re-check items 2 and 3 of the operational
procedures above when the IC does not move.
2. If the CXA3506R does not move even after item 1 above is checked, it is possible that the control signals of
the control register are not output from the PC printer board. In this case, be sure to re-check the board
settings listed for item 4 under "Program Installation and Startup".
