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.
