Non-Bonded Channel Configuration
In non-bonded channels, each channel in the ALTGX MegaWizard Plug-In Manager
instance contains its own tx_digitalreset, rx_analogreset,
rx_digitalreset, and rx_freqlocked signals.
You can reset each channel independently. For example, if there are four non-bonded
channels, the ALTGX MegaWizard Plug-In Manager provides four each of the
following signals: tx_digitalreset, rx_analogreset, rx_digitalreset, and
rx_freqlocked.

configuration under the stated functional modes.
Follow the same reset sequence for all the other channels in the non-bonded
configuration.
Transmitter Only Channel
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 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
high (marker 3), deassert the tx_digitalreset signal (marker 4). For the
receiver operation, after deassertion of the busy signal, wait for two parallel clock
cycles to deassert the rx_analogreset signal.
rx_locktorefclk and assert rx_locktodata (marker 7). At this point, the
receiver CDR of all the channels enters into lock-to-data mode and starts locking to
the received data.
deasserting rx_digitalreset (the time between markers 7 and 8). At this point,
the transmitter and receiver are ready for data traffic.
