CCD Imager Analog Processor

Features

Description

The CS7622 is a low-power analog front-end processor

for interline or frame transfer CCD imagers. Main appli-

cations include digital still image cameras and video

cameras.

l 13-Bit A/D Conversion Using DRX™

Technology

l Backlight Compensation

l Supports Full Scale Analog Input Voltage

Ranges from 300 mV to 1 V in 100 mV

Increments

l High Resolution Output Mode

l Low Resolution (Preview) Output Mode for

The architecture includes a correlated double sampler,

black level clamp and a 13-bit A/D conversion module

using patented DRX technology.

Chip parameters can be programmed using a high

speed 4-wire asynchronous digital interface.

LCD Driver

l Integrated Correlated Double Sampler

l Digital Black Level Clamp

The chip outputs digitized CCD data in either 13-bit, 12-

bit or 10-bit format. 10-bit outputs are generated from the

13-bit A/D output by a programmable companding curve.

l Digital Outputs Selectable for 13, 12, or 10 Bits

l Low Power Consumption

l Power Down Mode

l High Speed Serial Interface

l Supports a Large Variety of Clock Input

Frequencies

l Low power mode option
