HT82V70中文资料Two 6-Channel, up to 240MSPS CIS Timing Generator and Shading Correction数据手册Holtek规格书

描述 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.
