DIVIDER SELECTION TABLES
Mfin Divider Look-Up Tables (LUT)
The FIN_SEL1:0 pins select the feedback divider value
(“Mfin”). Since the VCSO frequency is fixed, this allows
input reference selection. The look-up tables vary by
device variant.
M2050/51/52: Mfin Value LUT
Mfec and Rfec Divider Look-Up Tables (LUTs)
The FEC_SEL pins select the Mfec/Rfec divider ratio.
The look-up tables vary by device variant. The Mfec
and Rfec values also establish phase detector
frequency. A lower phase detector frequency improves
jitter tolerance and lowers loop bandwidth.
