4.1.5. PIPE Transceiver Clocking

This section describes transceiver clocking for PIPE configurations.

PIPE x1 Configuration

The serial clock in the transceiver clocking configuration is provided by the CMU PLL in a channel different from that of the data channel. The local clock divider block in the data channel generates a parallel clock from this high-speed clock and distributes both clocks to the PMA and PCS of the data channel.

PIPE x4 Configuration

In a PIPE x4 bonded configuration, clocking is independent for the receiver channels. The clocking and control signals are bonded only for the transmitter channels.

PIPE x8 Configuration

In a PIPE x8 bonded configuration, the clocking for the PMA and PCS blocks is independent for the receiver channels. The clocking and control signals are bonded only for the transmitter channels.

For more information about clocking in Arria V devices, refer to the Transceiver Clocking in Arria V Devices chapter.
