Sony CXA3086Q 6-bit 140msps flash a/d converter Datasheet

CXA3086Q
6-bit 140MSPS Flash A/D Converter
Description
The CXA3086Q is an 6-bit high-speed flash A/D
converter capable of digitizing analog signals at the
maximum rate of 140MSPS. ECL, PECL or TTL can
be selected as the digital input level in accordance
with the application. The TTL digital output level
allows 1: 2 demultiplexed output.

Table 2. Operating Mode Table
1. DMUX mode (See Application Circuits (1), (2) and (3).)
Set the SELECT pin to Vcc for this mode. In this mode, the clock frequency is divided by 2 in the IC, and the
data is output after being demultiplexed by this 1/2 frequency divided clock. The 1/2 frequency divided clock,
which has adequate setup time and hold time for the output data, is output from the CLKOUT pin.
When resetting this 1/2 frequency divided clock, the low level of the RESET signal should be input to the
RESETN pin (Pin 10 or 12). The RESET signal requires the setup time (T_rs ≥ 3.5ns) and hold time (T_rh ≥
0ns) to the clock rising edge because it is synchronized with and taken in the clock. Therefore, set the RESET
signal to low for T_rs (min.) + T_rh (min.) = 3.5ns or longer to the clock rising edge.
The reset period can be extended by making the low level period of the RESET signal longer because the
clock output pin is fixed to low (reset) during the low level period at the clock rising edge. If the reset start
timing is regarded as not important, the timing where the RESET signal is set from high to low is not so
consequence. However, when the reset is released this timing must become significant because the timing is
used to commence the 1/2 frequency divided clock. In this case, the setup time (T_rs) is also necessary.
See the timing chart for detail. (This chart shows the example of reset for 2T.)
The A/D converter can operate at FC (min.) = 140MSPS in this mode.

2. Straight mode (See Application Circuits (4), (5) and (6).)
Set the SELECT pin to GND for this mode. In this mode, data output can be obtained in accordance with the
clock frequency applied to the A/D converter for applications which use the clock applied to the A/D converter
as the system clock.
The A/D converter can operate at Fc (min.) = 100MSPS in this mode.
Digital input level and supply voltage settings
The logic input level for the CXA3086Q supports ECL, PECL and TTL levels.
The power supplies (DVEE3, DGND3) for the logic input block must be set to match the logic input (CLK and
RESET signals) level.

CXA3086Q
Timing of A/D Converter and Peripheral Circuit
In the maximum clock rate of the DEMUX Mode, the timing of 3 channels of ADC CLK OUT in same phase is
described in detail as below.
For example, the CLK OUT from one of the ADC is used as the data latch clock. The clock delay and data
delay are showed in the following specification, i.e.
Td_clk
4.5ns (min.) to 8.0ns (max.)
Tdo2
6.5ns (min.) to 10ns (max.)
These values are considered in all the temperature change and power supply variation. When the maximum
clock rate 140MSPS is used, the set-up time (ts) is seemed to be very small from above specifications. But the
3 channels of ADC are in the same circuit board, so that the DATA OUT delay and CLK OUT delay will be
changed in same trend at the same condition of the temperature change and power supply variation. As a
result, 0.5ns of the delay will be faster, when the highest temperature and highest power supply is used. Also,
0.5ns of the delay will be later, when the lowest temperature and lowest power supply is used. These delay
can be omitted in this case.
When Ta = 25°C, VCC = +5V, the clock delay and data delay are
Td_clk
5.0ns (min.) to 7.5ns (max.)
Tdo2
7.0ns (min.) to 9.5ns (max.)
The timing of the DATA OUT and CLK OUT with above delay variation is showed in below. Consequently, the
set-up time for the data latching can be obtained as ts (min.) = 2.5ns. The output delay change of the DATA OUT
and CLK OUT due to the temperature change and the power supply variation should have the same trend of
the delay change, the minimum ts = 2.5ns can be guaranteed at any temperature change and power supply
variation.

CXA3086Q
Notes on Operation
• The CXA3086Q is a high-speed A/D converter which is capable of TTL, ECL and PECL level clock input.
Characteristic impedance should be properly matched to ensure optimum performance during high-speed
operation.
• The power supply and grounding have a profound influence on converter performance. The power supply
and grounding method are particularly important during high-speed operation. General points for caution are
as follows.
— The ground pattern should be as large as possible. It is recommended to make the power supply and
ground patterns wider at an inner layer using a multi-layer board.
— To prevent interference between AGND and DGND and between AVcc and DVcc, make sure the
respective patterns are separated. To prevent a DC offset in the power supply pattern, connect the AVcc
and DVcc lines at one point each via a ferrite-bead filter Shorting the AGND and DGND patterns in one
place immediately under the A/D converter improves A/D converter performance.
— Ground the power supply pins (AVcc, DVcc1, DVcc2, DVEE3) as close to each pin as possible with a
0.1µF or larger ceramic chip capacitor.
(Connect the AVcc pin to the AGND pattern and the DVcc1, DVcc2 and DVEE3 pins to the DGND pattern.)
— The digital output wiring should be as short as possible. If the digital output wiring is long, the wiring
capacitance will increase, deteriorating the output slew rate and resulting in reflection to the output
waveform since the original output slew rate is quite fast.
• The analog input pin VIN has an input capacitance of approximately 7pF. To drive the A/D converter with
proper frequency response, it is necessary to prevent performance deterioration due to parasitic capacitance
or parasitic inductance by using a large capacity drive circuit. keeping wiring as short as possible, and using
chip parts for resistors and capacitors, etc.
• The VRT and VRB pins must have adequate by-pass to protect them from high-frequency noise. By-pass them
to AGND with an approximately 1µF tantal capacitor and 0.1µF chip capacitor as short as possible.
• The offset for residual resistance is generated each for the reference voltage pins VRT and VRB.
When the offset voltage has no influence on the IC operation, the voltage should be applied to the VRT and
VRB pins directly, keeping the VRBS pin open. When the reference voltage is to be supplied to these pins
precisely, form the feedback loop circuit with VRT and VRB as a force pin and adjust the offset voltage to be
0V. See the “Application Circuit 2” for details.
• If the CLKN/E pin is not used, by-pass this pin to DGND with an approximately 0.1µF capacitor. At this time,
approximately DGND3 – 1.2V voltage is generated. However, this is not recommended for use as threshold
voltage VBB as it is too weak.
• When the digital input level is ECL or PECL level, ∗∗∗/E pins should be used and ∗∗∗/T pins left open. When
the digital input level is TTL, ∗∗∗/T pins should be used and ∗∗∗/E pins left open.

CXA3086Q Evaluation Board
Description
The CXA3086Q Evaluation Board is a special board designed to maximize and facilitate the evaluation
performance of the CXA3086Q. After latching the CXA3086Q output data with a frequency divided clock, the
analog signal can be regenerated by a 10-bit high-speed D/A converter. The latched data can also be
extracted externally via a 24-pin cable connector.

Notes on Board Operation
1.
The factory settings for the CXA3086Q Evaluation Board are as follows.
VRB.R1 = 1.5V
VRT.R2 = 3.0V
OFFSET.R3 = 2.25V
FULL SCALE.R4 = –1V
FULL SCALE.R5 = –1V
S1
S2
A : OPEN, B : SHORT
8 : SHORT (1/8 frequency division)
When using the board in this condition, the input signals should be input at the amplitudes shown below.
(The frequency is set as desired.)
Analog input signal: CON1 (AMP.IN)
0V center, 800mVp-p or less
Clock input signal: CON3 (CLK.IN)
0V center, 1.0Vp-p
2.
When the analog signal is input from the CON1 (AMP.IN) pin, IC2:CLC404 limits the input dynamic range
of the A/D converter's analog input signal.
3.
When the analog input signal is a sine wave or other repeating waveform, the signal can be input from the
CON2 (DIR.IN) pin with AC coupling. In these cases, the input dynamic range is not limited, but the VRT
level may be limited by IC3: NJM3403A.
4.
In the evaluation board of the CXA3086Q, CLC404 (Comlinear) is employed for IC2 to drive the analog
input signal. Though, CLC505 (Comlinear) can also be used instead of CLC404, there should be a little
change in the peripheral circuit in this case.
