Combining Channels Configured in Protocol Functional Modes

The following sections describe combining channels that are configured in protocol
functional modes.
The ALTGX MegaWizard Plug-In Manager provides a Basic mode with a ×4 option in
the Which sub-protocol will you be using? option on the General screen. If you
select this option, all the transmitter channels within the transceiver block receive the
high-speed serial and low-speed parallel clock from the CMU0 clock divider block
(present in the CMU0 channel). Each receiver channel within the transceiver block is
clocked independently by the recovered clock from its receiver CDR.
