GENERAL DESCRIPTION

The ADDI7004 is a highly integrated, quad-channel, HD image

signal processor for high speed imaging applications. Each channel

is specified at pixel rates of up to 72 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 220 ps

resolution at 72 MHz operation. The ADDI7004 also contains

a reduced range low voltage differential signaling (LVDS) inter-

face for the dual-channel data outputs.

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

a VGA, and a 72 MHz, 14-bit analog-to-digital converter (ADC).

Operation is programmed using a 3-wire serial interface.

Packaged in a space-saving, 6 mm × 6 mm, 76-ball BGA, the

ADDI7004 is specified over an operating temperature range of

−25°C to +85°C.
