1-2
Standard 10/100/1000Base-T/TX operation with forced or auto-negotiation for speed and duplex.
Automatic crossover (auto-MDIX) for straight-through and crossover connections.
Pause flow control as defined by the 802.3x standard.
Frame size of 9216 bytes.
Synchronous ENET operation that provides its recovered receive clock as an input clock source for
the SETS as well as uses the system-wide reference clock to derive its transmit clock.
100Base-FX and 1000Base-X SFP modules.
Copper SFP modules
Digital optical monitoring as specified by the SFP.
Any mix of SFPs is supported unless specifically noted.
Pause flow control as defined by the 802.3x standard.
Frame size of 9216 bytes.
Synchronous ENET operation that provides its recovered receive clock as an input clock source for
the SETS as well as uses the system-wide reference clock to derive its transmit clock.
Copper based SFPs do not support synchronous ENET operations.
Digital optical monitoring as specified by the optical transceiver module.
Any mix of SFPs is supported unless specifically noted.
Pause flow control as defined by the 802.3x standard.
