14-Bit CCD Signal Processor with

Precision Timing™ Generator

AD9970

FEATURES

GENERAL DESCRIPTION

1.8 V analog and digital core supply voltage

Serial data link with reduced range LVDS outputs

Correlated double sampler (CDS) with −3 dB, 0 dB, +3 dB,

and +6 dB gain

6 dB to 42 dB, 10-bit variable gain amplifier (VGA)

14-bit, 65 MHz ADC

The AD9970 is a highly integrated CCD signal processor for

high speed digital video camera applications. Specified at pixel

rates of up to 65 MHz, the AD9970 consists of a complete analog

front end with analog-to-digital conversion combined with a

programmable timing driver. The Precision Timing core allows

adjustment of high speed clocks with 240 ps resolution at

65 MHz operation. The AD9970 also contains a reduced range

LVDS interface for data outputs.

Black level clamp with variable level control

Complete on-chip timing generator

Precision Timing core with 240 ps resolution @ 65 MHz

On-chip, 3 V horizontal and RG drivers

5 mm × 5 mm, 32-lead LFCSP_VQ

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

and a 65 MSPS, 14-bit ADC. The timing driver provides the high

speed CCD clock drivers for RG, HL, and H1 to H4. Operation

is programmed using a 3-wire serial interface.

APPLICATIONS

Professional HDTV camcorders

Professional/high end digital cameras

Broadcast cameras

Packaged in a space-saving 5 mm × 5 mm, 32-lead LFCSP_VQ,

the AD9970 is specified over an operating temperature range of

−25°C to +85°C.

Industrial high speed cameras

High speed data acquisition systems
