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. 5 DELTA ELECTRONICS, INC. 2010/6/4 Rev. S0 www.deltaww.com 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 receives data path rate coverage for an SFP+ module. RS1 is an input hardware pin which optionally selects the optical transmits 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 outpit 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 dBo is recommended. 6 DELTA ELECTRONICS, INC. 2010/6/4 Rev.
