This configuration contains only a transmitter channel. If you create a Transmitter
Only instance in the ALTGX MegaWizard Plug-In Manager, use the same reset
sequence as shown in
Receiver Only Channel—Receiver CDR in Automatic Lock Mode
This configuration contains only a receiver channel. If you create a Receiver Only
instance in the ALTGX MegaWizard Plug-In Manager with the receiver CDR in
automatic lock mode, use the reset sequence shown in
As shown in
CDR in automatic lock mode configuration:
1. After power up, wait for the busy signal to be de-asserted (marker 1).
2. De-assert the rx_analogreset signal (marker 2).
3. Keep the rx_digitalreset signal asserted during this time period. After you
