High Speed, Correlated Double Sampler

with Integrated Timing Driver

AD9940

FEATURES

GENERAL DESCRIPTION

56 MSPS correlated double sampler (CDS) with 6 dB gain

On-chip horizontal and RG timing driver

Single-supply operation (2.7 V min )

Precision Timing™ core with 0.37 ns resolution at 56 MSPS

Low power CMOS: 105 mW at 2.7 V (115 mW at 3.0 V)

48-lead LQFP and 48-lead LFCSP packages

The AD9940 is a high speed, correlated double sampler for

high speed digital imaging applications. Integrated with a

programmable timing driver using the Precision Timing

core, the AD9940 features a 56 MHz CDS amplifier with

6 dB of fixed gain, an internal voltage reference supply,

and timing control for all the high speed clocks necessary

for CCD imaging systems. The Precision Timing core allows

adjustment of high speed clocks with a resolution of 0.37 ns.

Output buffers are also included, providing drive strength for

PCB traces and direct connection to an image signal processor

such as the AD9941.

APPLICATIONS

Professional HDTV camcorders

Professional/high end digital cameras

Broadcast cameras

Industrial high speed cameras

High speed data-acquisition systems

The AD9940 is ideal for applications that need to place the

CDS and VGA/ADC circuits on separate PC boards. The fully

differential outputs of the AD9940 provide good signal integ-

rity when interfaced with the differential input AD9941. The

AD9940 operates from a single 2.7 V power supply, typically

dissipates 105 mW (excluding the H/RG drive current), and is

packaged in 48-lead LQFP and 48-lead LFCSP packages.
