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.
