14-Bit, CCD Signal Processor with  
Precision Timing™ Core  
AD9979  
FEATURES  
GENERAL DESCRIPTION  
1.8 V analog and digital core supply voltage  
Correlated double sampler (CDS) 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  
Black-level clamp with variable level control  
Complete on-chip timing generator  
The AD9979 is a highly integrated CCD signal processor for  
high speed digital video camera applications. Specified at pixel  
rates of up to 65 MHz, the AD9979 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.  
Precision Timing core with 240 ps resolution @ 65 MHz  
On-chip 3 V horizontal and RG drivers  
General-purpose outputs (GPOs) for shutter and system  
support  
7 mm × 7 mm, 48-lead LFCSP package  
Internal LDO regulator circuitry  
The analog front end includes black-level clamping, CDS, VGA,  
and a 65 MSPS, 14-bit analog-to-digital converter. The timing  
driver provides the high speed CCD clock drivers for RG, HL,  
and H1 to H4. Operation is programmed using a 3-wire serial  
interface.  
Available in a space-saving, 7 mm × 7 mm, 48-lead LFCSP  
package, the AD9979 is specified over an operating temperature  
range of −25°C to +85°C.  
APPLICATIONS  
Professional HDTV camcorders  
Professional/high end digital cameras  
Broadcast cameras  
Industrial high speed cameras
