Driver circuit for CMOS linear image sensor C10808 series High-precision driver circuit with variable integration time function The C10808 series is a driver circuit specifically designed for the HAMAMATSU S10111 to S10114, S10121 to S10124 series current-output type CMOS linear image sensors. The C10808 series driver circuit supplies various timing signals necessary for image sensor operation and also processes analog video signal from an image sensor with low noise. All that is needed to operate the C10808 series driver circuit are two external control signals (MStart, MCLK) and a power supply (±15 V).

When the INT signal is set to “high” at signal readout timing of a specified pixel, then no signal is output from that pixel and integration continues. Using this function to lengthen the integration time of specified pixels, making it possible to effectively detect weak light signal components.

Then set the EXT-INT signal to either of the pixel output level (high level) or pixel integration level (low level) for every output period (every 4 MCLK pulses) of each pixel, and input it to the driver circuit. The integration time of each pixel can be changed by setting the EXT-INT signal level every 4 MCLK pulses in the interval from the second MCLK pulse after the START-EX (MStart) signal is set to the low level to the 4n + 2MCLK (n: number of pixels of CMOS linear image sensor to be used). The P-INT signal is generated inside the circuit and is used to output the INT signal by OR (logical addition) on the inverted EXT-INT signal. Therefore, the sensor operates in normal mode when the EXT-INT signal is fixed at the high level or CN3 is not connected. 4(n-1) + 2 MCLK (CLK-EX) MStart (START-EX) 1 2 3 4 5 6 7 8 4n + 2 9 10 11 12 ST CLK P-INT EXT-INT INT Data Video 1 ch output MCLK MStart 2 ch integration 3 ch integration n-1 ch output n ch output <EXT-INT signal setting> Set the EXT-INT signal level to low or high every 4 MCLK pulses from the rising edge of the second MCLK pulse after the MStart signal is set to the low level.
