GENERAL DESCRIPTION
The AD9974 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. The AD9974
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 approximately 240 ps resolution at 65 MHz operation.
Each analog front end includes black level clamping, CDS, VGA,
and a 65 MSPS, 14-bit ADC. The timing driver provides the high
speed CCD clock drivers for the RG_A, RG_B, H1_A to H4_A,
and H1_B to H4_B outputs. A 3-wire serial interface is used to
program each channel of the AD9974.
Available in a space-saving, 9 mm × 9 mm, CSP_BGA package,
the AD9974 is specified over an operating temperature range of
25°C to +85°C.
