Table 1A. Frequencies, Dividers, and Gear Ratios
A: Feedback divider in the DRCG PLL.
B: Refclk divider in the DRCG PLL
M: Pclk divider in the gear ratio logic.
N: synclk divider in the gear ratio logic.
Table 1A above shows several supported Pclk and Busclk frequencies, the corresponding A and B dividers required
Ratio as defined by Pclk/Synclk (same as M/N). The column the Phase Detector, where
F@PD
= Pclk/M = Synclk/N.
Table 1B below show examples of CLK/CLKB frequencies for different DRCG input frequencies.
