GENERAL DESCRIPTION

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.

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.

The AD9927 is specified over an operating temperature range

of –25°C to +85°C.
