Description
FSCTR
0x16[3:0]
W
Filter Sample Rate Selection.
Since impedance matching is done thru the use of a switched capacitor
filter, the realized impedance is exact only if Sample Rate Frequency (Fs)
matches to the Sample Rate specified in FSCTR(3:0). When the actual
sample rate is not any one of the followings in the table, a setting closest
to the actual Fs should be chosen to minimize mismatching errors. These
setting will affect both in AC Impedance Matching Filter (IPMF) and
Receiver Low Pass Notch Filter (RLPN) both.
