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  
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.  
1.8 V analog and digital core supply voltage  
Serial data output with reduced range LVDS outputs  
Differential analog inputs  
CDS or SHA configuration (CDS bypass) with  
−3 dB, 0 dB, +3 dB, and +6 dB gain  
6 dB to 42 dB, 10-bit variable gain amplifier (VGA)  
14-bit, 65 MHz analog-to-digital converter (ADC)  
Black level clamp with variable level control  
Precision Timing core with 240 ps resolution @ 65 MHz  
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.  
APPLICATIONS  
Digital video cameras  
Digital still cameras  
Digital copiers  
Multifunction printers  
High speed industrial cameras  
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.
