Description
AI
The AD9974 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. The AD9974 consists of a complete analog front end with analog-to-digital conversion combined with a programmable timing driver. ThePrecision Timingcore allows adjustment of high speed clocks with approximately 240 ps resolution at 65 MHz operation.Each analog front end includes black level clamping, CDS, VGA, and a 65 MSPS, 14-bit ADC. The timing driver provides the high speed CCD clock drivers for the RG_A, RG_B, H1A to H4A, and H1B to H4B outputs. A 3-wire serial interface is used to program each channel of the AD9974.Available in a space-saving, 9 mm × 9 mm, CSP_BGA package, the AD9974 is specified over an operating temperature range of −25°C to +85°C.APPLICATIONSProfessional HDTV camcordersProfessional/high-end digital camerasBroadcast camerasIndustrial high speed cameras
