1.2.3 Transmit PLL

The PolarFire transmit PLL (PF_TX_PLL) is a hard IP block that provides a bit clock and a reference clock to the transceiver block. The transmit PLL is configured with a reference clock of 156.25 MHz and generates an output clock of 10312.5 Mbps. The clock option is set to Jitter cleaning mode to enable the Jitter attenuator PLL.

The following figure shows the transmit PLL configuration.
