FEATURES
Dual-Channel, 16-Bit HD Image Signal
Processor with
Precision Timing
Core
ADDI7018
GENERAL DESCRIPTION
The
ADDI7018
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
ADDI7018
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 75 MHz, 16-bit analog-to-digital converter (ADC).
Operation is programmed using a 3-wire serial interface.
Packaged in a space-saving, 6 mm × 6 mm, 40-lead LFCSP, the
ADDI7018
is specified over an operating temperature range of
−25°C to +85°C.
