GENERAL DESCRIPTION
The AD9974 is a highly integrated, dual-channel, charge-
coupled device (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 (AFE) 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 AFE 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.
