AD9978BCPZ

双通道， 14位CCD信号处理器， Precision Timing内核 Dual-Channel, 14-Bit CCD Signal Processor with Precision Timing Core

Product Details

The AD9978 is a highly integrated, dual-channel CCD signal processor for high speed digital video camera applications. Each channel is specified at pixel rates of up to 65 MHz and consists of a complete analog front end with ADC conversion. The _Precision Timing_™ core allows adjustment of the correlated double sampler CDS and sample-and-hold amplifier SHA clocks with 240 ps resolution at 65 MHz operation. The AD9978 also contains a reduced range, low voltage differential signaling LVDS interface for the dual-channel data outputs.

Each analog front end includes black level clamping, a CDS, a VGA, and a 65 MHz, 14-bit ADC. Operation is programmed using a 3-wire serial interface.

Packaged in a space-saving, 6 mm × 6 mm, 40-lead LFCSP, the AD9978 is specified over an operating temperature range of −25°C to +85°C.

**Applications**

* Digital video cameras

* Digital still cameras

* Digital copiers

* Multifunction printers

* High speed industrial cameras
