DC Offset Calibration Counter

BIT

DESCRIPTION

C(0-6)

Least Significant bit C(0) to Most significant bit C(6) of the offset calibration counter/divider. The calibration clock frequency and

calibration time is defined by the Reference signal frequency divided down by this counter as follows:

CAL TIME = 22 ∗ R-----E----F--2--I-N--∗----(--CM-----H-----z---)

C(11)

Set output bias level for AC coupling applications and TX/RX switching improvement in performance.
