1.2.3.2. Fractional PLL (fPLL)

A fractional PLL (fPLL) is an alternate transmit PLL used for generating lower clock frequencies for 12.5 Gbps and lower data rate applications. fPLLs support both integer frequency synthesis and fine resolution fractional frequency synthesis. Unlike the ATX PLL, the fPLL can also be used to synthesize frequencies that can drive the core through the FPGA fabric clock networks.
