Receiver and Transmitter Channel—Receiver CDR in Automatic Lock Mode
This configuration contains both a transmitter and a receiver channel. If you create a
Receiver and Transmitter instance in the ALTGX MegaWizard Plug-In Manager with
the receiver CDR in automatic lock mode, use the reset sequence shown in
