GENERATOR

GENERAL DESCRIPTION

The AD9923A is a complete 36 MHz front-end solution for

digital still cameras and other CCD imaging applications.

Similar to the AD9923 product, the AD9923A includes the

analog front end (AFE), a fully programmable timing generator

(TG), and a 15-channel vertical driver (V-driver). A Precision

Timing core allows adjustment of high speed clocks with

approximately 600 ps resolution at 36 MHz operation.

The on-chip V-driver supports up to 15 channels for use with

5-field, 10-phase CCDs.

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

and a 12-bit ADC. The timing generator and V-driver provide

all the necessary CCD clocks: RG, H-clocks, vertical clocks, sensor

gate pulses, substrate clock, and substrate bias control. The

internal registers are programmed using a 3-wire serial

interface.

Packaged in an 8 mm × 8 mm CSP_BGA, the AD9923A is

specified over an operating temperature range of −25°C to +85°C.
