Notes:

1.Module circuit ground is isolated from module chassis ground within the module.

2.should be pulled up with 4.7k – 10k ohms on host board to a voltage between 3.15Vand 3.6V.

3.Tx_Disable is an input contact with a 4.7 kΩ to 10 kΩ pullup to VccT inside the module.

4.Mod_ABS is connected to VeeT or VeeR in the SFP+ module. The host may pull this contact up to Vcc_Host with a resistor in the range 4.7 kΩ to10 kΩ.Mod_ABS is asserted “High” when the SFP+ module is physically absent from a host slot.

5. RS0 and RS1 are module inputs and are pulled low to VeeT with > 30 kΩ resistors in the module.

 

Digital Diagnostic Specifications

 

The transceivers can be used in host systems that require either internally or externally calibrated digital diagnostics.

 

Parameter	Symbol	Units	Min.	Max.	Accuracy	Note
Transceiver temperature	DTemp-E	ºC	-45	+90	±5ºC	1,2
Transceiver supply voltage	DVoltage	V	2.8	4.0	±3%
Transmitter bias current	DBias	mA	0	127	±10%	3
Transmitter output power	DTx-Power	dBm	-2	+3	±2dB
Receiver average input power	DRx-Power	dBm	-20	+1	±2dB

Notes:

1.When Operating temp.=0~70 ºC,the range will be min=-5,Max=+75

2. Internally measured

3. The accuracy of the Tx bias current is 10% of the actual current from the laser driver to the laser

 

Typical Interface Circuit

 

 

 

Recommended power supply filter

 

 

 

Note:

Inductors with DC resistance of less than 1Ω should be used in order to maintain the required voltage at the SFP input pin with 3.3V supply voltage. When the recommended supply filtering network is used, hot plugging of the SFP transceiver module will result in an inrush current of no more than 30 mA greater than the steady state value
