The AD9948 is a highly integrated CCD signal processor that is designed for digital still camera applications. The device features a 10-bit 25 MSPS A/D converter and a complete on-chip timing driver with high-precision time-alignment capability, and can operate at 3 V.
The AD9948 is a highly integrated CCD signal processor designed for digital still camera applications. It combines a complete analog front end with A/D conversion and a programmable timing driver in a single device.
The analog front end includes black level clamping, Correlated Double Sampling (CDS), Pixel Gain Amplifier (PxGA), Variable Gain Amplifier (VGA), and a 10-bit 25 MSPS A/D converter. The precision timing core allows for high-speed clock adjustment with 800 ps resolution, while the on-chip driver provides clocks for RG and H1–H4 outputs.
