Chapter 1: Cyclone IV Transceivers Architecture 1–41
Transceiver Clocking Architecture

For Transmitter and Receiver operation in bonded channel configuration, the receiver
PCS supports configuration with rate match FIFO, and configuration without rate
match FIFO. Figure 1–39 shows the datapath clocking in Transmitter and Receiver
operation with rate match FIFO in ×2 and ×4 bonded channel configurations. For
Transmitter and Receiver operation in bonded channel configuration without rate
match FIFO, the datapath clocking is identical to Figure 1–38 for the bonded
transmitter channels, and Figure 1–34 on page 1–35 for the receiver channels.
