Mfec and Rfec Divider Look-Up Tables (LUTs)  
DIVIDER SELECTION TABLES  
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.  
Mfin Divider Look-Up Tables (LUT)  
The FIN_SEL1:0 pins select the feedback divider value  
(“Mfin”), which sets the overall PLL ratio range. Since  
the VCSO frequency is fixed, this allows input reference  
selection. The look-up tables vary by device variant.
