Description
charge pump current: 0 = large; 1 = small
de-emphasis: 0 = 50 s; 1 = 75 s
LNA feedback resistor: 0 = 1 M ; 1 = 2.2 M
Description
selection bit: 0 = C[6:0] sets C-bank; 1 = C[6:0] sets C-align
C[6:0] sets C-bank or C-align word depending upon bit CALLIGN:
Description
search mode: 0 = disabled; 1 = enabled
copy word: 0 = no copy; 1 = copy PLL word to BLIM register
if bit PROGBLIM = 0: 0 = down search; 1 = up search
if bit PROGBLIM = 1: 0 = lower band limit; 1 = upper band limit
