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 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 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. 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.
