LCP-6144B4MDRx
Note:
1. The module signal ground pins, VeeR and VeeT, shall be isolated from the module case.
2. This pin is an open collector/drain output pin and shall be pulled up with 4.7k-10k ohms to Host_Vcc
on the host board. Pull ups can be connected to multiple power supplies, however the host board
design shall ensure that no module pin has voltage exceeding module VccT/R + 0.5V.
3. This pin is an open collector/drain input pin and shall be pulled up with 4.7k-10k ohms to VccT in the
Module.
4. This pin shall be pulled up with 4.7k-10k ohms to Host_Vcc on the host board.
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 > 30k
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.
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.
