4.6. Gigabit-Capable Passive Optical Network (GPON)

The GPON protocol network provides optical fiber cabling and signals to the home and office using a point-to-multipoint scheme. GPON data rates of 155.52 Mbps, 622.08 Mbps, 1.24416 Gbps, and 2.48832 Gbps, with a reference clock of 155.52 MHz are supported. The minimum supported data rate is 600 Mbps, so a 5x oversampling factor is used for the GPON data rate of 155.52 Mbps, resulting in a data rate of 777.6 Mbps.
Note: You must build the oversampling at the PLD.
