This configuration contains only a transmitter channel. If you create a Transmitter
Only instance in the ALTGX MegaWizard Plug-In Manager in Basic ×4 functional
mode, use the reset sequence shown in

As shown in
reset steps:
1. After power up, assert pll_powerdown for a minimum period of t

de-assert the pll_powerdown signal, the transmitter PLL starts locking to the
transmitter input reference clock.
