Description
Signal
1MEG to VDD and decouple to GND Pixel source follower bias current
1MEG to GND and decouple to VDD Column amp 1st source follower (after SHY)
bias current
1MEG to GND and decouple to VDD Column amp current source bias current
100K to VDD and decouple to GND X-multiplexing bias current (/6)
low active (0=sync)
0 = reset right shift register
Shifts on falling edge
clock right shift register
Active low
low 1st clk_yr pulse after last row
Active low
low 1st clk_x pulse after last active column
input selector for output amplifier
1 = external input; [0] = imager core
Analog GND
Analog VDD
+ 5 V DC
external input to output amplifier
analog output of imager core
Connect to in_adc (p73)
