3-CHANNEL 16-BIT LINEAR CCD/CIS SENSOR SIGNAL PROCESSOR
REV. 1.0.1

* Power-on default lt value
PD - Power Down. Does not affect the internal register settings but does power down the entire part
excluding the serial interface. There will be some power up settling time required to
reestablish the ADC reference, CAPP and CAPN, voltages.
OE - Output Enable. Tristate control for the output data bus.
LPOL - LCLMP input polarity select. (Noninverting pol active high, inverted pol active low)
ADCPOL - ADCLK polarity select. (Noninverting pol begins high, inverted pol begins low)
BPOL - BSAMP polarity select. (Noninverting pol active high, inverted pol active low)
VPOL - VSAMP polarity select. (Noninverting pol active high, inverted pol active low)

BSAMP Delay Register
The BSAMP Delay register controls the internal delays added to the leading and the trailing edges of the
BSAMP timing signal. The width and position of the BSAMP pulse can be adjusted through the leading and
trailing edge delay settings. This is useful to match the sampling requirements of the incoming CCD waveform.
* Power-on default value
BL[4:0] - Sets the amount of delay added to the leading edge of BSAMP.
BT[4:0] - Sets the amount of delay added to the trailing edge of BSAMP.
