Description
AI
The AD9972 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 40 MHz. The AD9972 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 400 ps resolution at 40 MHz operation.Each analog front end includes black level clamping, CDS, VGA, and a 40 MSPS, 14-bit ADC. The timing driver provides the high speed CCD clock drivers for the RG_A, RG_B, H1_A to H4_A, and H1_B to H4_B outputs. A 3-wire serial interface is used to program each channel of the AD9972.Available in a space-saving, 9 mm × 9 mm, CSP_BGA package, the AD9972 is specified over an operating temperature range of −25°C to +85°C.ApplicationsProfessional HDTV camcordersProfessional/high end digital camerasBroadcast camerasIndustrial high speed cameras
