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.
