Start-up of Power Supply and Reset
It is necessary to reset the I2C bus interface immediately when it is supplied with power. When reset, the I2C bus
interface releases its SDA line and becomes operative. In addition, its write register is previously loaded with an initial
value.
<1> When the power is switched on, wait until the power supply line reaches and settles on a 3.3-V/2.5-V level
before starting initialization.
<2> Initialize the I2C bus interface circuit by keeping the RSTB pin at a low level for at least 10 µs.
<3> Start communication on the I2C bus interface after 100 µs from pull up the RSTB pin to a high level.

Video Signal Inputs
The composite signal is input to the AYI pin. This analog video (composite) signal converts to digital video signal at
internal 10-bit ADC (EXADINS = 0).
In case of external ADC used, 10-bit composite signals in digital form are input to the DYCO9 to DYCO0 pins
(EXADINS = 1).
3.2
Pedestal Level Reproduction
This circuit reproduces the pedestal level of a video signal. The pedestal level error detection circuit detects the
difference between that level and the internal fixed value of 256 LSB levels, and outputs the feedback level.
This output signal is connected to VCLY pin via internal resistor to feed back to video signal for fixing pedestal level
to 256 LSB. Pull down the VCLY pin via a 0.1 µF bypass capacitor and a 10 to 47 µF electrolysis capacitor for loop
filter.
Caution In case of H-Sync input level is bigger than 256LSB, this pedestal level also becomes over 256LSB.
Do not use this circuit when the external ADC is used.

Video Signal Input Level
It is necessary to limit the level of video (composite) signal inputs to within a certain range to cope with the maximum
amplitude of the video signal and variations in it. Figure 3-2 shows the waveform of the video signal input whose
amplitude is 140 IREp-p = 820 LSB (0.8 times a maximum input range of 1024 LSB). In this case, it is possible to input a
white level of up to 131 IRE for the Y signal and up to 175 IREp-p for the C signal.

Pin Treatment
•
Supply 2.5 V to the AVDD pins. Isolate them sufficiently from the digital section power supply.
•
Use as wide wiring patterns as possible for the ground lines of each bypass capacitor and the AGND pins so as
to minimize their impedance.
•
•
Connect a video signal to the AYI pin by capacitive coupling. Maintain low input impedance for video signals. Be
sure to keep the wiring between the capacitor and the AYI pin as short as possible.
Pull down the VRTY, VRBY and VCOMY reference voltage pins via a 0.1 µF bypass capacitor.
•
Pull down the VCLY pin via a 0.1 µF bypass capacitor and a 10 to 47 µF electrolysis capacitor.
•
Do not bring the digital system wiring (especially the memory system) close to this block and the straight
downward of the IC.

External ADC Connection Method
Setting up EXADINS = 1 on the serial bus puts the IC in the external ADC mode. In this mode, the ALTF pin is used
to output 4fSC sampling clock pulses, and the DYCO9 to DYCO0 pins are used to receive digital data inputs. Setting up
ST0S = 01 on the serial bus causes a clamp pulse to be output from the ST0 pin. It is used as a pedestal clamp pulse
for external ADC. The clamp potential for the pedestal level of external ADC must be determined so that the sampled
value becomes about 256 ±8LSB. Supply converted 10-bit data to the DYCO9 to DYCO0 pins via a 100 Ω resistor. For
using 8-bit ADC (exp. µPC659A), Pull down the DYCO1 and DYCO0 pins via 100 Ω resistor.
In this mode, for ADC in the µPD64084, keep the VRTY, VRBY and VCOMY pins open, and pull down the VCLY and
AYI pins via a 0.1 µF capacitor.

Sync Separator and Timing Generator
These sections separate horizontal and vertical sync signals from the composite signal sampled at 4fSC or 910fH,
and generate system timing signals by using them as references.
4.2
Composite Sync Signal Input
An active-low composite sync signal separated from the video signal is input at the CSI pin. This input is used as a
reference signal to lock onto sync at the timing generator.
4.3
Horizontal/Burst Phase Detection Circuit
The horizontal phase detection circuit extracts the horizontal sync signal from the Y signal sampled at 4fSC or 910fH
to detect a horizontal phase error. This phase error is used for generation of 227.5fH and timing generator. The burst
phase detection circuit extracts the burst signal from the composite signal sampled at 4fSC to detect a burst phase error.
This phase error is used for fSC generation.
4.4
PLL Filter Circuit
The PLL filter circuit integrates a burst or horizontal phase error to determine the oscillation frequency of the fSC
generator ahead.
4.5
Killer Detection Circuit
The killer detection circuit compares the amplitude of the burst signal with the KILR value set on the serial bus to
judge on a color killer. If the burst amplitude becomes smaller than or equal to the set KILR value when the burst
locked clock is operating, the fSC generator is allowed to free-run.
17
Data Sheet S16021EJ2V0DS
µ PD64084
4.6
fSC Generator
The fSC generator generates fSC (or 227.5fH when the line locked clock is running) from an oscillation frequency
determined in the PLL filter. fSC is converted by internal DAC to an analog sine waveform before it is output from the
FSCO pin. Because this output contains harmonic components, they must be removed using an external band-pass
filter (BPF) connected via a buffer, before the analog sine waveform is input to the FSCI pin via a capacitor. The fSC
generator uses a 20 MHz free-run clock pulse as a reference.
4.7
8fSC-PLL Circuit
The 8fSC-PLL circuit generates 8fSC (or 1820fH) from fSC (or 227.5fH) input at the FSCI pin. The 8fSC signal is output
from the CLK8 pin. It is also used as the internal system clock.

•
Supply 2.5 V to the AVDD pins. Isolate them sufficiently from the digital section power supply.

•
Connect a 20-MHz Crystal resonator across the XI and XO pins. Provide guard areas using ground patterns to
keep these pins from interfering with other blocks. Table 4-1 shows the crystal resonator specification example.

Line Comb Filter
The C signal is separated from video signals that have been delayed by 0H, 1H, and 2H. This filter serves as a
logical comb filter based on inter-line correlation to reduce dot and cross-color interference. The filter output (C2) is
used in the moving picture portion of standard signals, nonstandard signals, and blanking periods.
5.2
Frame Comb Filter
The C signal is separated from video signals that have been delayed by 1H and 526H. The filter output (C3) is used
in still picture portions by the motion detection circuit.
5.3
Mixer Circuit
The mixer circuit mixes C signals to adapt to the motion according to the motion factor from the motion detection
circuit. In other words, COUT is generated by mixing the line comb filter output (C2) and the frame comb filter output (C3)
by a mixture ratio according to the motion factor k (0 to 1). If the input signal is a nonstandard signal, or if the LINE pin
is at a high level, C2 is output without performing motion-adaptive mixture.
5.4
C Signal Subtraction
The YOUT signal is separated by subtracting the COUT signal from a composite video signal that has been delayed by
1H.
Subtraction is quitted when the killer detection circuit detects that the input signal is a color killer signal
(monochrome signal or non-burst signal) or that the KIL pin is at an 'H' level.

Before obtaining an inter-frame difference, the line comb filter performs Y/C separation for the composite signals of
both frames.
6.2
DY Detection Circuit
The DY detection circuit detects a Y signal inter-frame difference. After a Y signal difference between the current
and previous frames is obtained, its absolute value, obtained by limiting the frequency band for the Y signal difference
using an LPF, is output as a Y frame difference signal, or a DY signal.
6.3
DC Detection Circuit
The DC detection circuit detects a C signal inter-frame difference. After a C signal difference between the current
and previous frames is obtained, its absolute value, obtained by limiting the frequency band for the C signal difference
using an LPF, is output as a C frame difference signal, or a DC signal. Because the phase of the C signal is inverted
between frames, the absolute values of the C signals of both frames have been obtained before the difference is
obtained.
6.4
Motion Factor Generation Circuit
The motion factor generation circuit generates a 4-bit motion factor from the DY and DC signals. The first coring
circuit performs coring according to the DYCOR and DCCOR settings on the serial bus to block weak signals like noise.
The gain adjustment circuits ahead perform gain adjustment according to the DYGAIN and DCGAIN settings on the
serial bus to specify the sensitivity of the motion factor. These outputs are limited to a 4-bit width, and one having a
higher level is selected for output by the maximum value selection circuit. The selected signal is expanded horizontally,
then output as a final motion factor.
6.5
Forcible Control for The Motion Factor
The motion factor can be set to 0 (forced stop) or a maximum value (forced motion) using the MSS signal on the
serial bus.

YNR/CNR Processing
The frame difference (∆Y) signal is generated by subtracting the previous frame Y signal from the current frame Y
signal. The noise component ∆Y' signal is extracted by eliminating the motion component of the ∆Y signal at the
nonlinear filter. Noise components are reduced by subtracting the noise component ∆Y' signal from the current frame Y
signal. At the same time, the Y signal submitted to noise reduction is delayed by a frame to be used to generate ∆Y for
the next frame. This way the frame recursive YNR is configured. Much the same processing is performed for the C
signal to reduce noise components.
7.2
Nonlinear Filter
The ∆Y' and ∆C' noise components are extracted from ∆Y and ∆C.
∆Y and ∆C contain inter-frame motion
components and noise components. Subtracting ∆Y and ∆C from the current frame Y and C signals causes inter-frame
motion components to remain in the output picture. To solve this problem, a nonlinear filter that passes only lowamplitude signals is used; generally, motion components have a large amplitude, while noise components have a small
amplitude. How nonlinear the filter is to be is specified using YNRK, YNRLIM, YNRINV, CNRK, CNRLIM, and CNRINV
on the serial bus.
7.3
YNR/CNR Operation Stop
If the nonstandard signal detection circuit detects a vertical nonstandard signal or frame sync nonstandard signal, or
the LINE pin is at a high level, the killer detection circuit detects a color killer signal, or the KIL pin is at a high level,
YNR and CNR operations are stopped.

read using OHSDF on the serial bus.
8.2
Vertical Sync Nonstandard Signal Detection
The vertical sync nonstandard signal detection circuit detects signals not having a standard relationship between fH
and fV (fH = 262.5fV) like a VCR special playback signal and home TV game signal. The sensitivity of detection cannot

result can be read using OVSDF on the serial bus.
8.3
Frame Sync Nonstandard Signal Detection
The frame sync nonstandard signal detection circuit detects signals out of horizontal sync phase between frames,
such as a laser-disc special playback signal. The sensitivity of detection is set using LDSR on the serial bus. If the

read using LDSDF on the serial bus.

It is possible to specify either forced standard or nonstandard signal control using NSDS on the serial bus.

The noise level detection circuit detects a noise level in the flat portion of a video signal. The sensitivity of detection
is set using WSCOR on the serial bus. The detection result can be read using WSL on the serial bus; it is not used in

the serial bus. The gain to be added can be changed in 16 steps over a range
between −1.000 times and +0.875 times.
<4> Addition to the main line : Y peaking components, together with vertical aperture compensation components,
are added to the Y signal.
10.3 Vertical Aperture Compensation Circuit
The vertical aperture compensation circuit extracts vertical contour components from a Y signal and adds them to
the Y signal to emphasize contours.
<1> Line comb filter
: Extracts vertical high-frequency components from the video signal.
<2> LPF circuit
: Eliminates C signal components and Y signal slant components to extract vertical
contour components.
<3> Coring circuit
: Performs ±1LSB (in 8-bit terms) coring for vertical high-frequency components to
prevent S/N deterioration during aperture compensation.
<4> Gain adjustment circuit : Performs gain adjustment for aperture compensation components according to the
VAPGAIN setting on the serial bus.
<5> Limiter circuit (nonlinear processing) :
Performs limit processing for aperture compensation components according to the
VAPINV setting on the serial bus. Signals for which contours are to be emphasized
are rather weak ones.
Uniform emphasis would result in initially large signals
becoming too large. To solve this problem, the limiter circuit blocks signals larger
than the VAPINV setting, thereby disabling contour emphasis for large signals.
<6> Addition to the main line : Vertical aperture compensation components, together with Y peaking components,
are added to the Y signal.
10.4 Turning On/Off Y Peaking and Vertical Aperture Compensation
The YAPS setting on the serial bus can be used to turn Y peaking and vertical aperture compensation on and off.
10.5 ID-1 Encoder
Bit information conforming to the ID-1 standard (CPX-1204) can be superimposed on the Y signal output at
20H/283H.
ID1ENON on the serial bus specifies whether to turn on or off superimposition.
ID1ENW0A1 and
ID1ENW0A2 specify the bit information to be superimposed.
If ID-1 information has already be superimposed on the original signal, it will be replaced with the newly specified
ID-1 information.

(−280 ns) and +3 clock pulses (+210 ns).
11.2 BPF and Gain Processing

12.1 Digital YC Output Processing
When setting up DYCOS = 00 on the serial bus, DYCO9 (MSB) to DYCO0 (LSB) pins alternately output 10 bits of Y
signals in straight binary and 10 bits of C signals in offset binary. And ALTF pin outputs alternative flag of Y or C
signals. When ALTF = 'L' means "C Signal Outputs", when ALTF = 'H' means "Y Signal Outputs".
When setting up DYCOS = 1x on the serial bus, DYCO9 (MSB) to DYCO0 (LSB) and ALTF pins are high-impedance.
When the DYCO pins are not used, setting DYCOS = 1x on the serial bus reduces radiation noise of these pins.
When the external ADC is used, DYCO9 to DYCO0 pins are used as the digital input terminal of video signal. So the
digital YC output is not available.

13.1 Usage of extend digital I/O terminals
The extended digital I/O pin EXTDYCO9 to EXTDYCO0 becomes effective by setting serial bus to EXTDYCO = 1.
At this time, internal ADC can not be available. The I/O mode selection of EXTDYCO9 to EXTDYCO0 are set by
serial bus DYCOS.
When using input mode of DYCOn or EXTDYCOn pins, insert serial resistor in the lines.
13.2 Digital YC output format
The specification of the digital input and output for the extended digital I/O pin EXTDYCO9 to EXTDYCO0 is same as
usual digital I/O pin DYCO9 to DYCO0. When using in input mode, input 10-bit digitized composite video signal that is
sampled by 4fsc. And when using in output mode, EXTDYCO9 (MSB) to EXTDYCO0 (LSB) pins alternately output 10
bits of Y signals in straight binary and 10 bits of C signals in offset binary. And EXTALTF pin outputs alternative flag of
Y or C signals. When ALTF = 'L' means "C Signal Outputs", when ALTF = 'H' means "Y Signal Outputs".
The internal ADC and extended digital I/O can’t work at the same time. And extended digital I/O pins have 3.3 V
resistant.

14. DIGITAL CONNECTION WITH GHOST REDUCER IC µ PD64031A
The µ PD64084 can perform processing from ghost reduction to three-dimension Y/C separation digitally in 10-bit
units when it is directly connected to NEC Electronics' ghost reducer IC µ PD64031A.
Figure 14-1 shows the system configuration when the µ PD64031A and µ PD64084 are digitally connected directly.
14.1 Outline
When signals are input from a ground wave tuner, the composite video signal is first input to the A/D converter of the
µ PD64031A, where the ghost of the signal is reduced. The digital clamp circuit then adjusts the pedestal level, and the
digital amplifier circuit adjusts the amplitude of the signal. As a result, a 10-bit digital composite video signal is sent to
the three-dimension Y/C separation IC µ PD64084. The µ PD64084 then performs processing such as Y/C separation
and outputs a Y/C video signal that has been converted into an analog signal (see Figure 14-1).

14.2 System Configuration and Control Method
14.2.1
Selecting video signal input path
When a video signal is input from a tuner or external pin, the input path of the video signal must be selected. This
selection is made by a serial bus register of the µ PD64084. If the signal is input from a tuner when the ghost reducer is
used, a digital video signal input pin is selected by the µ PD64084. When signals are input from other external pins
(such as those of a VCR, DVD, video camera, or game machine), the internal A/D converter of the µ PD64084 is made
valid, so that the video signal directly input to the µ PD64084 becomes valid.
For details on how to set the pins and registers, see Table 14-1 and Table 14-2 in Section 14.3.
14.2.2 Selecting mode according to clock and video signal input path
When the µ PD64031A and µ PD64084 are digitally connected directly, the system clock must be shared by the two
ICs. When the ghost reducer is used (when signals are input from a tuner), the µ PD64031A generates burst lock clock
fSC, as shown in Figure 14-1. This fSC goes through an external BPF and is input to the 8fSC PLL of the µ PD64084,
where system clocks (8fSC and 4fSC) are generated. These system clocks are used by the µ PD64084, and are also
supplied to the µ PD64031A by the µ PD64084 from the CLK8 pin.
When the ghost reducer is not used (when signals are input from an external source), the video signal is not input to
the µ PD64031A, and only the µ PD64084 operates. It is therefore necessary that the burst clock generated by the
µ PD64084 be used.
To switch the path of inputting fSC to the fSC BPF between the FSCO pin of the µ PD64031A and the FSCO pin of the
µ PD64084, an analog switch is necessary in the input block of the fSC BPF.
This analog switch is controlled by the WP1 pin of the µ PD64031A. The WP1 pin is controlled by register DIR3DYC
(SA08h: D7 and D6) of the µ PD64031A (that selects a three-dimension Y/C separation digital connection mode). By
changing the setting of this register depending on whether the ghost reducer is used or not, the analog switch can be
controlled by the signal output from the WP1 pin. In this way, the fSC path can be changed.
A 20-MHz crystal oscillator that generates the basic clock for the fSC generator should be provided to the
µ PD64031A. When the ghost reducer is not used and the µ PD64084 operates alone, the 20-MHz clock output from
the C20O pin of the µ PD64031A is used.
For details on how to set the pins and registers, see Table 14-1 and Table 14-2 in Section 14.3.

15. I C BUS INTERFACE
15.1 Basic Specification
The I2C bus is a two-wire bi-directional serial bus developed by Philips. It consists of a serial data line (SDA) for
communication between ICs and a serial clock line (SCL) for establishing sync in communication.

The following procedure is used to transfer data from the master IC to a slave IC.
<1> Start condition : To start communication, hold the SCL at a high level, then pull down the SDA from a high to a
low level.
<2> Data transfer
: To transfer data, pull up the SCL from a low to a high, while holding the current state of the
SDA. Data transfer is carried out in units of 9 bits, that is, 8 data bits (D7 to D0, MSB first) plus
an acknowledgment bit (ACK). A selected slave IC sets the SDA to a low when it receives bit
9 to send acknowledgment.
<3> Stop condition : To terminate communication, pull up the SDA from a low to a high upon acknowledgment,
while keeping the SCL at a high.

15.2 Data Transfer Formats
Immediately when the master IC satisfies the start condition, each slave receives a slave address. If the received
slave address matches that of a slave IC, communication begins between the slave IC and the master IC. If not, the
SDA line is released. Two sets of slave addresses can be specified according to the SLA pin.

NOTES FOR CMOS DEVICES
1
PRECAUTION AGAINST ESD FOR SEMICONDUCTORS
Note:
Strong electric field, when exposed to a MOS device, can cause destruction of the gate oxide and
ultimately degrade the device operation. Steps must be taken to stop generation of static electricity
as much as possible, and quickly dissipate it once, when it has occurred. Environmental control
must be adequate. When it is dry, humidifier should be used. It is recommended to avoid using
insulators that easily build static electricity. Semiconductor devices must be stored and transported
in an anti-static container, static shielding bag or conductive material. All test and measurement
tools including work bench and floor should be grounded. The operator should be grounded using
wrist strap. Semiconductor devices must not be touched with bare hands. Similar precautions need
to be taken for PW boards with semiconductor devices on it.

HANDLING OF UNUSED INPUT PINS FOR CMOS
Note:
No connection for CMOS device inputs can be cause of malfunction. If no connection is provided
to the input pins, it is possible that an internal input level may be generated due to noise, etc., hence
causing malfunction. CMOS devices behave differently than Bipolar or NMOS devices. Input levels
of CMOS devices must be fixed high or low by using a pull-up or pull-down circuitry. Each unused
pin should be connected to V DD or GND with a resistor, if it is considered to have a possibility of
being an output pin. All handling related to the unused pins must be judged device by device and
related specifications governing the devices.
3
STATUS BEFORE INITIALIZATION OF MOS DEVICES
Note:
Power-on does not necessarily define initial status of MOS device. Production process of MOS
does not define the initial operation status of the device. Immediately after the power source is
turned ON, the devices with reset function have not yet been initialized. Hence, power-on does
not guarantee out-pin levels, I/O settings or contents of registers. Device is not initialized until the
reset signal is received. Reset operation must be executed immediately after power-on for devices
having reset function.
