     Notes:

     Plug Seq.: Pin engagement sequence during hot plugging. 

    1) TX Fault is not supported and is always connected to ground. 

    2) TX Disable is not supported. 

    3) Mod-Def 0, 1, 2. These are the module definition pins. They should be pulled up with a 4.7K to 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

     4) LOS is not supported in 10/100/1000base-T  

    5) 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.

     6) TD-/ : These are the differential transmitter inputs. They are AC-coupled, differential lines with 100 differential termination inside the module. 

3.3V Volt Electrical Power Interface 

    Has an input voltage range of 5V /- 5%. The 3.3V maximum voltage is not allowed for continuous operation.

Parameter	Symbol	Min	Typ	Max	Units	Notes/Conditions
Supply Current	Is		320	375	mA	1.2W max power over full range of voltage and temperature. See caution note below
Input Voltage	Vcc	3.13	3.3	3.47	V	Referenced to GND
Maximum Voltage	Vmax			4	V
Surge Current	Isurge			30	mA	Hot plug above steady state current. See caution note below

     Caution: Power consumption and surge current are higher than the specified values in the SFP MSA 

Low-Speed Signals 

    MOD_DEF (1) (SCL) and MOD_DEF (2) (SDA), are open drain CMOS signals (see section VII, “Serial 

    Communication Protocol”). Both MOD_DEF (1) and MOD_DEF (2) must be pulled up to host_Vcc.

Mechanical Specifications 

    The host-side of the SPT-PE-T1 conforms to the mechanical specifications outlined in the SFP MSA1. 

    The front portion of the SFP (part extending beyond the face plate of the host) is larger to accommodate the 

    RJ-45 conector.
