PRODUCT DESCRIPTION
The AD9848 and AD9849 are highly integrated CCD signal pro-
cessors for digital still camera applications. Both include a complete
analog front end with A/D conversion, combined with a program-
mable timing driver. The
Precision Timing
core allows adjustment
of high speed clocks with approximately 1 ns resolution.
The AD9848 is specified at pixel rates of 20 MHz, and the
AD9849 is specified at 30 MHz. The analog front end includes
black level clamping, CDS,
PxGA
, VGA, and a 10- or 12-bit A/D
converter. The timing driver provides the high-speed CCD clock
drivers for RG and H1-H4. Operation is programmed using a
3-wire serial interface.
Packaged in a space-saving 48-lead LQFP, the AD9848 and
AD9849 are specified over an operating temperature range of
–20
°
C to +85
°
C.
