Quad-Channel, 16-Bit CCD Signal Processor with Core

The ADDI7015 is a highly integrated, quad-channel, CCD signal processor for high speed digital imaging applications. Each channel is specified at pixel rates of up to 60 MHz and consists of a complete analog front end (AFE) with ADC conversion. The Precision Timing™ core allows adjustment of the correlated double sampler (CDS) and sample-and-hold amplifier (SHA) clocks with 260 ps resolution at 60 MHz operation. There are eight independent horizontal clock outputs to support a variety of CCD timing requirements. The ADDI7015 also contains programmable ISATG for vertical timing generation.

Each analog front end includes black level clamping, a CDS, a VGA, and a 60 MSPS 16-bit analog-to-digital converter (ADC). Operation is programmed using a 4-wire serial interface.

Packaged in a space-saving, 8 mm × 8 mm, CSPBGA, the ADDI7015 is specified over an operating temperature range of −25°C to +85°C.
