GENERAL DESCRIPTION

The AD9942 is a highly integrated dual-channel CCD signal

processor for digital still camera applications. Each channel is

specified at pixel rates of up to 40 MHz. The AD9942 consists of

a complete analog front end with analog-to-digital conversion,

combined with a programmable timing driver. The Precision

Timing core allows high speed clocks to be adjusted with

550 ps resolution.

The analog front end uses black level clamping and includes a

VGA, a 40 MSPS ADC, and a CDS. The timing driver provides

the high speed CCD clock drivers for RG_A and RG_B, as well

as the H1A to H4A and H1B to H4B outputs. The 6-wire serial

interface is used to program the AD9942.

Available in a space-saving, 9 mm × 9 mm, CSP_BGA package,

the AD9942 is specified over an operating temperature range of

−25°C to +85°C.
