Sony CXA3506R Datasheet

3-channel 8-bit 120MSPS A/D Converter Amplifier PLL

Description

The CXA3506R is a 3-channel 8-bit 120MSPS A/D
converter with built-in amplifier and PLL developed
for LCD projectors and LCD monitors.

The CXA3506R inputs RGB graphics signals from
personal computers or others. After the input levels
are controlled, the A/D conversion is performed with
a clock generated by PLL.

The digital output levels are compatible with TTL.

This IC operates at a maximum conversion rate of
120MHz, and can support up to XGA. Control register
supports both I2C and 3-wire bus.

Features

• Supply voltage: 5V, 3.3V

• Power consumption: 1.7W typ. (120MSPS)

• 144-pin LQFP

• 3-ch AMP and PLL eliminate design time for mutual

connections.

Equivalent circuit Description

Power supply for amplifier block.

GND 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 AV

CC.

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.

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 AV

CCAMP.

Input via a 0.1µF ceramic capacitor.
The typical signal level is 0.7V.
Signals from 0.5V (min.) to

1.0V (max.) can be supported.
IN1 and IN2 are selected by the
control register.
Leave these pins open when not
used.
RGB input and YCbCr input can be
selected by the control register.

The clamp level typical values are
as follows.
In case RGB is input

2.2V + Vf (0.8V) =
approximately 3V

In case YCbCr is input

G/YIN:

2.2V + Vf (0.8V) =
approximately 3V

R/CrIN, B/CbIN:

2.7V + Vf (0.8V) =
approximately 3.5V

Clamp period: A clamp current of
±1.2mA (max.) flows.
Signal period: A base current of

0.5µA flows to the IC.
