GENERAL DESCRIPTION
The AD9973 is a highly integrated dual channel CCD signal
processor for high speed digital video camera applications.
Each channel is specified at pixel rates of up to 65 MHz, and
consists of a complete analog front end with analog-to-digital
conversion, combined with a programmable timing driver. The
Precision Timing core allows adjustment of high speed clocks
with 240 ps resolution at 65 MHz operation. The AD9973 also
contains a reduced range LVDS interface for the dual-channel
data outputs.
Each analog front end (AFE) includes black level clamping,
CDS, VGA, and a 65 MSPS, 14-bit analog-to-digital converter.
The timing driver provides the high speed CCD clock drivers for
RG, HL, and H1 to H4. Operation is programmed using a
3-wire serial interface.
Packaged in a space-saving 6 mm × 6 mm, 84-ball CSP_BGA,
the AD9973 is specified over an operating temperature range of
−25°C to +85°C.
