CCD Signal Processor with

Precision Timing^™Generator

AD9937

FEATURES

GENERAL DESCRIPTION

12 MSPS Correlated Double Sampler (CDS)

10-Bit 12 MHz A/D Converter

No Missing Codes Guaranteed

6 dB to 40 dB Variable Gain Amplifier (VGA)

Black Level Clamp with Variable Level Control

Complete On-Chip Timing Generator

Precision Timing Core with 1.7 ns Resolution

On-Chip: 6-Channel Horizontal and 1-Channel RS Drivers

4-Phase Vertical Transfer Clocks

The AD9937 is a highly integrated CCD signal processor. It

includes a complete analog front end with A/D conversion,

combined with a full-function programmable timing generator.

A Precision Timing core allows adjustment of high speed clocks

with 1.7 ns resolution at 12 MHz operation.

The AD9937 is specified at pixel rates of up to 12 MHz. The

analog front end includes black level clamping, CDS, VGA, and

a 10-bit A/D converter. The timing generator provides all the

necessary CCD clocks: RS, H-clocks, V-clocks, sensor gate pulses,

and substrate charge reset pulse. Operation is programmed using a

3-wire serial interface.

Electronic and Mechanical Shutter Modes

On-Chip Sync Generator with External Sync Option

APPLICATIONS

Digital Still Cameras

Industrial Imaging

The AD9937 is packaged in a 56-lead LFCSP and specified over

an operating temperature range of –25°C to +85°C.
