Notes:
1. Internally ac coupled and terminated (100 Ohm differential). These levels are compatible with CML and LVPECL voltage swings.
2. Internally ac coupled with an external 100 ohm differential load termination.
3. Represents nominal output voltage. User may change values through register 26.2:0. Please refer to Table 19 for output settings.
4. 20%-80% rise and fall times measured from the module’s internally generated Gigabit Ethernet idle pattern at 1.25 Gbps.
5. Tx Disable function as described in the SFP MSA is not used in the 1000BASE-T module.
6. Time from rising edge of Tx Disable until link comes down.
7. Time from falling edge of Tx Disable until auto-negotiation starts.
