GENERAL DESCRIPTION

The AD9920A is a highly integrated charge-coupled device (CCD)

signal processor for digital still camera applications. It includes a

complete analog front end (AFE) with analog-to-digital conversion,

combined with a full-function programmable timing generator

and 19-channel vertical driver (V-driver). The timing generator

is capable of supporting up to 26 vertical clock signals to control

advanced CCDs. The on-chip V-driver supports up to 19 channels

for use with 6-field CCDs. A Precision Timing™ core allows adjust-

ment of high speed clocks with approximately 400 ps resolution

at 40.5 MHz operation. The AD9920A also contains six GPOs

that can be used for shutter and system functions.

The analog front end includes black level clamping, variable

gain CDS, and a 12-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 AD9920A is specified over an operating temperature range

of −25°C to +85°C.
