Part Details:

12-Bit CCD Signal Processor with Precision Timing Core AD9949 FEATURES GENERAL DESCRIPTION New AD9949A supports CCD line length > 4096 pixels The AD9949 is a highly integrated CCD signal processor for Correlated double sampler (CDS) digital still camera applications. Specified at pixel rates of up to 0 dB to 18 dB pixel gain amplifier (PxGA®) 36 MHz, the AD9949 consists of a complete analog front end 6 dB to 42 dB 10-bit variable gain amplifier (VGA) with A/D conversion, combined with a programmable timing 12-bit, 36 MSPS analog-to-digital converter (ADC) driver. The Precision Timing core allows adjustment of high Black level clamp with variable level control speed clocks with < 600 ps resolution. Complete on-chip timing driver Precision TimingTM core with < 600 ps resolution The analog front end includes black level clamping, CDS, On-chip 3 V horizontal and RG drivers PxGA, VGA, and a 36 MSPS, 12-bit ADC. The timing driver 40-lead LFCSP package provides the high speed CCD clock drivers for RG and H1 to H4. Operation is programmed using a 3-wire serial interface. APPLICATIONS Packaged in a space-saving, 40-lead LFCSP package, the Digital still cameras AD9949 is specified over an operating temperature range of High speed digital imaging applications -20°C to +85°C.
