Description
AI
The AD9942 is a highly integrated dual-channel CCD signal processor for digital still camera applications. Each channel is specified at pixel rates of up to 40 MHz. The AD9942 consists of a complete analog front end with analog-to-digital conversion, combined with a programmable timing driver. ThePrecision Timing™ Core allows high speed clocks to be adjusted with 550 ps resolution.The analog front end uses black level clamping, and includes a VGA, a 40 MSPS ADC, and a CDS. The timing driver provides the high speed CCD clock drivers for RG_A, RG_B, as well as the H1A to H4A and H1B to H4B outputs. The 6-wire serial interface is used to program the AD9942.Available in a space-saving, 9 mm x 9 mm, CSP_BGA package, the AD9942 is specified over an operating temperature range of −25°C to +85°C.ApplicationsSignal processor for dual-channel CCD outputsDigital still camerasDigital video camerasHigh speed digital imaging applications
