4.1.6 Transmit PLL

The transmit PLL reference clock and desired output clock are set to 125 MHz and 5156.25 MHz respectively,as shown in the following figure. The PolarFire transceiver is a half-rate architecture, which is the internal high-speed path uses both edges of the clock to keep the clock rates down. The clock thus runs at half of the data-rate, thereby consuming less dynamic power.

The following figure shows the Transmit PLL configurator.
