To use this feature, you must create an ALTGX instance with a single channel in
Transmitter Only mode that uses the required CMU PLL or ATX PLL. To create the
ALTGX instance, follow these steps:
1. Choose Basic (PMA Direct) ×N mode as the protocol.
2. Select Transmitter Only operation mode.
3. Select the input clock frequency.
4. Select the appropriate values of data rate and channel width based on the desired
Equation 2–1.
5. You can select the PLL bandwidth by choosing Tx PLL bandwidth mode.
6. You can instantiate the pll_locked port to indicate the PLL lock status.
7. You can instantiate pll_powerdown or gxb_powerdown to enable the PLL PFD power
8. Use tx_clkout of the ALTGX instance as the clock source for clocking user logic in
