Product Details
●The AD9977 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 A/D conversion combined with a programmable timing driver. The _Precision Timing_ core allows adjustment of high speed clocks with 240 ps resolution at 65 MHz operation. The AD9977 also contains a reduced range LVDS interface for the dual-channel data outputs.
●Each analog front end includes black level clamping, CDS, VGA, and a 65 MSPS, 14-bit A/D 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.
●Packaged in a space-saving 6 mm × 6 mm, 84-ball CSP_BGA package, the AD9977 is specified over an operating temperature range of −25°C to +85°C.
