Notes:
1. The output swing and pre-emphasis levels are programmable using the GTY transceiver attributes and can result in values
lower than reported in this table.
2. V_{RX_TERM} is the remote RX termination voltage.
3. Other values can be used as appropriate to conform to specific protocols and standards.
