GENERAL DESCRIPTION
The AD9978 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 ADC conversion. The Precision
Timing™ core allows adjustment of the correlated double sampler
(CDS) and sample-and-hold amplifier (SHA) clocks with 240 ps
resolution at 65 MHz operation. The AD9978 also contains a
reduced range, low voltage differential signaling (LVDS) interface
for the dual-channel data outputs.
Each analog front end includes black level clamping, a CDS,
a VGA, and a 65 MHz, 14-bit ADC. Operation is programmed
using a 3-wire serial interface.
Packaged in a space-saving, 6 mm × 6 mm, 40-lead LFCSP, the
AD9978 is specified over an operating temperature range of
−25°C to +85°C.
