14-Bit CCD Signal Processor with V-Driver

and Precision Timing^TMGenerator

AD9927

FEATURES

GENERAL DESCRIPTION

Integrated 18-channel V-driver

1.8 V AFETG core

Internal LDO regulator and charge pump circuitry

Compatibility with 3 V or 1.8 V systems

24 programmable vertical clock signals

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, 40 MHz analog-to-digital converter (ADC)

Black level clamp with variable level control

Complete on-chip timing generator

The AD9927 is a highly integrated CCD signal processor for

digital still camera applications. It includes a complete analog

front end with A/D conversion, combined with a full-function

programmable timing generator and 18-channel vertical driver

(V-driver). The timing generator is capable of supporting up to

24 vertical clock signals to control advanced CCDs. The on-

chip V-driver supports up to 18 channels for use with 5-field

CCDs. A Precision Timing core allows adjustment of high speed

clocks with approximately 400 ps resolution at 40 MHz

operation. The AD9927 also contains eight general-purpose

outputs, which can be used for shutter and system functions.

Precision Timing core with ~400 ps resolution

On-chip 3 V horizontal and RG drivers

General-purpose outputs (GPOs) for shutter and

system support

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

and a 14-bit ADC. The timing generator provides all the

necessary CCD clocks: RG, H-clocks, V-clocks, sensor gate

pulses, substrate clock, and substrate bias control.

On-chip driver for external crystal

On-chip sync generator with external sync input

128-lead CSP_BGA package, 9 mm × 9 mm, 0.65 mm pitch

The AD9927 is specified over an operating temperature range

of –25°C to +85°C.
