Sony CXA3516R Datasheet

3-channel 8-bit 165MSPS A/D Converter Amplifier PLL

Description

The CXA3516R is a 3-channel 8-bit 165MSPS A/D converter with built-in amplifier and PLL developed for LCD projectors and LCD monitors.

The CXA3516R 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 165MHz, and can support up to UXGA. Control register supports both I2C and 3-wire bus.

Features

• Supply voltage: 5V, 3.3V

• Power consumption: 1.8W typ. (165MSPS)

• 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.
