1.2.1. Transceiver Bank Architecture
Each transceiver bank includes six transceiver channels in all devices except for the devices with 66 transceiver channels. Devices with 66 transceiver channels have both six channel and three channel transceiver banks. The uppermost transceiver bank on the left and the right side of these devices is a three channel transceiver bank. All other devices contain only six channel transceiver banks.
The figures below show the transceiver bank architecture with the phase locked loop (PLL) and clock generation block (CGB) resources available in each bank.
The transceiver channels perform all the required PHY layer functions between the FPGA fabric and the physical medium. The high speed clock required by the transceiver channels is generated by the transceiver PLLs. The master and local clock generation blocks (CGBs) provide the necessary high speed serial and low speed parallel clocks to drive the non-bonded and bonded channels in the transceiver bank.
