Dual-Channel, 14-Bit HD Image Signal

Processor with Precision Timing Core

AD9978A

FEATURES

GENERAL DESCRIPTION

Dual AFE channels

The AD9978A is a highly integrated, dual-channel, charge-

coupled device (CCD) signal processor for high speed digital

video camera applications. Each channel is specified at pixel

rates of up to 75 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 210 ps resolution at

75 MHz operation. The AD9978A also contains a reduced range

low voltage differential signaling (LVDS) interface for the dual-

channel data outputs.

1.8 V analog and digital core supply voltage

Serial data output with reduced range LVDS outputs

Differential analog inputs

CDS or SHA configuration (CDS bypass) with

−3 dB, 0 dB, +3 dB, and +6 dB gain

6 dB to 42 dB, 10-bit variable gain amplifier (VGA)

14-bit, 75 MHz analog-to-digital converter (ADC)

Black level clamp with variable level control

Precision Timing core with 210 ps resolution @ 75 MHz

Each analog front end includes black level clamping, a CDS,

a VGA, and a 75 MHz, 14-bit analog-to-digital converter (ADC).

Operation is programmed using a 3-wire serial interface.

APPLICATIONS

Digital video cameras

Digital still cameras

Digital copiers

Multifunction printers

High speed industrial cameras

Packaged in a space-saving, 6 mm × 6 mm, 40-lead LFCSP, the

AD9978A is specified over an operating temperature range of

−25°C to +85°C.
