3.3. Frequency Plan Tables
The Si5323 provides flexible frequency plans for SONET, Datacom, and interworking between the two (Table 8,
Table 9, and Table 10 respectively). Both CKINn inputs must be the same Fin frequency and CKOUTn outputs as
specified in the tables.
The following notes apply to Tables 8, 9, and 10:
1. All multiplication ratios are exact, but the frequency values are rounded.
2. For loop bandwidth settings, BWSEL[1:0], f3 values, and frequency operating ranges, consult the DSPLLsim

software configuration utility.
