NOTES:
1. VIN+ AND VIN– SIGNALS ARE SAMPLED AT DATACLK RISING EDGES (CAN BE INVERTED USING THE CONTROL REGISTER).
2. INTERNAL SAMPLING DELAY (APERTURE)
3. OUTPUT DATA LATENCY IS NINE DATACLK CYCLES.
NOTES:
1. CLPOB WILL OVERWRITE PBLK. PBLK WILL NOT AFFECT CLAMP OPERATION IF OVERLAPPING CLPOB.
2. PBLK SIGNAL IS OPTIONAL.
3. DIGITAL OUTPUT DATA WILL BE ALL ZEROS DURING PBLK. OUTPUT DATA LATENCY IS NINE DATACLK CYCLES.
