It includes a complete analog front end with analog-to-digital conversion and a full-function programmable timing generator for a 2-channel output CCD. Each channel is specified up to 32 MHz. The timing generator is capable of supporting up to 24 vertical clock signals to control advanced CCDs. A Precision Timing™ core allows adjustment of high speed clocks with approximately 488 ps resolution at 32 MHz operation. The AD9990 also contains eight general-purpose outputs that can be used for shutter and system functions. Each analog front end includes black level clamping, a CDS, a VGA, and a 14-bit ADC. The timing generator provides all the necessary CCD clocks: RG, H-clocks, V-clocks, sensor gate pulses, substrate clock, and substrate bias control. The AD9990 is specified over an operating temperature range of −25°C to +85°C. For more information about the AD9990, contact Analog Devices via email at afe.ccd@analog.com.
