Notes:
Plug Seq.: Pin engagement sequence during hot plugging.
Application Notes
Loss of Signal (LOS): LVTTL compatible with a
maximum voltage of 2.5V. LOS pin can enabled or
disabled (Refer to Ordering information).
TX_Fault: TX_Fault pin is not supported, and is always
connected to ground.
TX_Disable: It is an input used to reset the transceiver
module. This pin is pulled up within the module with a 4.7
0.8 V): Transceiver on; Between 0.8
V and 2.0 V: Undefined; High (2.0
3.465 V): Transceiver
in reset state; Open: Transceiver in reset state.
Serial Identification and Monitoring: The module
definition of SFP is indicated by the three module
definition
pins,
MOD_DEF(0),
MOD_DEF(1)
and
MOD_DEF(2).
They should be pulled up with a 4.7K~10K resistor on the
host board. The pull-up voltage shall be VccT or VccR.
MOD_DEF(0) is grounded by the module to indicate that
the module is present. MOD_DEF(1) is the clock line of
two wire serial interface for serial ID. MOD_DEF(2) is the
data line of two wire serial interface for serial ID.
RD-/+: These are the differential receiver outputs. They
are AC coupled 100 differential lines which should be
terminated with 100 (differential) at the user SERDES.
TD-/+: These are the differential transmitter inputs. They
are AC-coupled, differential lines with 100 differential
terminations inside the module.
