LCP-10G3A4EDRx-G
Low speed electrical control pins and 2-wire interface
In addition to the 2-wire serial interface, the SFP+ module has the following low speed pins for control and
status:
‧ TX_Fault
‧ TX_Disable
‧ RS0/RS1
‧ MOD_ABS
‧ RX_LOS
1 TX_Fault
TX_Fault is a module output pin that when High, indicates that the module transmitter has detected a fault
condition related to laser operation or safety.
The TX_Fault output pin is an open drain/collector and must be pulled p to the Host_Vcc with 4.7k-10k
ohms on the host board
2 TX_Disable
TX_Disable is a module input pin. When TX_Disable is asserted High or Left open, the SFP+ module
transmitter output must be turned off. The TX_DIS pin must be pulled up to VccT in the SFP+ module..
3 RS0/RS1
RS0 and RS1 are module input rate select pins and are pulled low to VeeT with a > 30kΩ resistor in the
module. RS0 is an input hardware pin which optionally selects the optical receive data path rate coverage
for an SFP+ module. RS1 is an input hardware pin which optionally selects the optical transmit path data
rate coverage for an SFP+ module. RS1 is commonly connected to VeeT or VeeR in the legacy SFP
modules. The host needs to ensure that it will not be damaged if this pin is connected to VeeT or VeeR in
the module.
4 MOD_ABS
Mod_ABS is pulled up to Host_Vcc with 4.7k-10k ohms on the host board and connected to VeeT or VeeR
in the SFP+ module. MOD_ABS is then asserted “High” when the SFP+ module is physically absent from
a host slot. In the SFP MSA (INF8074i) this pin had the same function but is called MOD_DEF0.
5 SCL/SDA
SCL is the 2-wire interface clock and SDA is the 2-wire interface data line. SCL and SDA are pulled up to
a voltage in the range of 3.14V to 3.46V on the host.
6 RX_LOS
RX_LOS when High indicated an optical signal level below that specified in the relevant standard. The
RX_LOS pin is an open drain/collector output and must be pulled up to host Vcc with a 4.7k-10k ohms on
the host board.
RX_LOS assert min and de-assert max are defined in the relevant standard. To avoid spurious transition
of RX_LOS a minimum hysteresis of 0.5 dB is recommended.

Notes:
1)
Rising edge of TX_Disable to fall of output signal below 10% of nominal.
2)
Falling edge of TX_Disable to rise of output signal above 90% of nominal. This only applies in normal
operation, not during start up or fault recovery.
3)
From power on or negation of TX_Disable.
4)
From power on or TX_Disable negated during power up, or TX_Fault recovery, until non-cooled power
level 1 part (or non-cooled power level 2 part already enabled at power level 2 for TX_Fault recovery)
is fully operational.
5) From falling edge of stop bit enabling power level 2 until non-cooled module is fully operational.
6) From falling edge of stop bit disabling power level 2 until module is within power level 1 requirements.
7) From Occurrence of fault to assertion of TX_Fault.
8) Time TX_Disable must be held High to reset TX_Fault.
9) From assertion till stable output.
10) From Occurrence of loss of signal to assertion of LOS
11) From Occurrence of presence of signal to negation of RX_LOS.
