General Description
The HT82V70 is a fully integrated device for CIS
imaging application. It features programmable timing
generator and image sensor shading correction to
sample and condition the outputs of CIS (Contact
Image Sensor) arrays for high-speed double-sided
scanner applications.
With up to two AFE HT82V48 ICs, it can support
two 3~6-channel inputs up to 240MSPS. Intelligent
image sensor shading correction is then employed on
each sensor element. The sensor data can be not only
corrected but also averaged per line for black level
calculations. The Video Processing Front End (VPFE)
Interface multiplexed shaded ADC’s outputs two
high-bytes for each ADC’s output or one 16-bit wide
output for each ADC. A pixel clock PCLK transports
the 16-bit wide data to the output port.
The internal registers are programmed through a
2-wire I2C or 3-wire/4-wire SPI interface, for timing
control, gain, offset and operating mode adjustments.
