Overview
The AD9949AKCPZ is a highly integrated 12-Bit CCD Signal Processor designed by Analog Devices Inc. for digital still camera applications. It operates at pixel rates of up to 36 MHz and features a complete analog front end with A/D conversion, combined with a programmable timing driver. The Precision Timing core allows for high-speed clock adjustments with a resolution of less than 600 ps. The device is packaged in a 40-lead LFCSP package and operates over an operating temperature range of −20°C to +85°C.
