PRODUCT DESCRIPTION
The AD9891 and AD9895 are highly integrated CCD signal
processors for digital still camera applications. Both include a
complete analog front end with A/D conversion combined with
a full-function programmable timing generator. A
Precision
Timing
core allows adjustment of high speed clocks with 1 ns
resolution at 20 MHz operation and 700 ps resolution at 30
MHz operation.
The AD9891 is specified at pixel rates of up to 20 MHz, and
the AD9895 is specified at 30 MHz. The analog front end
includes black level clamping, CDS,
PxGA
, VGA, and a 10-Bit
or 12-Bit A/D converter. The timing generator provides all the
necessary CCD clocks: RG, H-clocks, V-clocks, sensor gate
pulses, substrate clock, and substrate bias control. Operation is
programmed using a 3-wire serial interface.
Packaged in a space-saving 64-lead CSPBGA, the AD9891 and
AD9895 are
specified over an operating temperature range of
–
20
°
C to +85
°
C.
