Note 1: PLL_MULT[3:0] bits are found in bits 11:8 and 3:0 in register SERDES_PLL_CONFIG at address 4/5.36864.
Note 2: RATE[1:0] bits are found in the SERDES_RATE_CONFIG_TX_RX register at address 4/5.36865.
Note that REFCLK is limited to 187.5 Mhz when in full rate mode to achieve 3750 Mbps serial data rate.
