2)
AC coupled inside transceiver. Must be terminated with 100
differential at the user SERDES.
3)
A logic 0 switches the transmitter on. A logic 1 switches the transmitter off.
4)
AC coupled and 100
differential termination inside the transceiver.

In accordance to SFF Committee SFF-8079 Draft.
8)
Mounting Studs are provided for transceiver mechanical attachment to the circuit board. They also provide an
optional connection of the transceiver to the equipment chassis ground.
9)
The transceiver Housing Leads are provided for additional signal grounding. The holes in the circuit board must
be included and be tied to signal ground (see
EMI Recommendations
).
