Part Details:

Dual-Channel, 14-Bit CCD Signal Processor with Precision Timing Core AD9978 FEATURES GENERAL DESCRIPTION Dual AFE channels The AD9978 is a highly integrated, dual-channel CCD signal 1.8 V analog and digital core supply voltage processor for high speed digital video camera applications. Each Serial data output with reduced range LVDS outputs channel is specified at pixel rates of up to 65 MHz and consists of Differential analog inputs a complete analog front end with ADC conversion. The Precision CDS or SHA configuration (CDS bypass) with TimingTM core allows adjustment of the correlated double sampler -3 dB, 0 dB, +3 dB, and +6 dB gain (CDS) and sample-and-hold amplifier (SHA) clocks with 240 ps 6 dB to 42 dB, 10-bit variable gain amplifier (VGA) resolution at 65 MHz operation. The AD9978 also contains a 14-bit, 65 MHz analog-to-digital converter (ADC) reduced range, low voltage differential signaling (LVDS) interface Black level clamp with variable level control for the dual-channel data outputs. Precision Timing core with 240 ps resolution @ 65 MHz Each analog front end includes black level clamping, a CDS, APPLICATIONS a VGA, and a 65 MHz, 14-bit ADC. Operation is programmed Digital video cameras using a 3-wire serial interface. Digital still cameras Packaged in a space-saving, 6 mm × 6 mm, 40-lead LFCSP, the Digital copiers AD9978 is specified over an operating temperature range of Multifunction printers -25°C to +85°C.
