Product Descriptions

The transceiver Enhanced Small Form Factor Pluggable SFP+ transceivers are designed for use in 10-Gigabit Ethernet links up to 10km over SingleMode fiber. They are compliant with SFF-8431,SFF-8432 and IEEE 802.3ae 10GBASE-LR/LW. The transceiver designs are optimized for high perform-ance and cost effective to supply customers the best solutions for telecommunication.

Functional Diagram

Absolute Maximum Ratings

Note: Stress in excess of the maximum absolute ratings can cause permanent damage to the transceiver.

General Operating Characteristics

Electrical Characteristics (TOP(C) = -20 to 75 ℃, TOP(I) =-40 to 85 ℃,VCC = 3.13 to 3.47 V)

Note:

1. Connected directly to TX data input pins. AC coupling from pins into laser driver IC.

2. Into 100Ω differential termination.

3. 20 – 80%. Measured with Module Compliance Test Board and OMA test pattern. Use of four 1’s and four 0’s sequence in the PRBS 9 is an acceptable alternative.

4. LOS is an open collector output. Should be pulled up with 4.7kΩ – 10kΩ on the host board. Normal operation is logic 0; loss of signal is logic 1.

Optical Characteristics (TOP(C) = -20 to 75 ℃, TOP(I) =-40 to 85 ℃,VCC = 3.13 to 3.47 V)

Notes:

1. Average power figures are informative only, per IEEE 802.3ae.

2. Valid between 1260 and 1355 nm. Measured with worst ER; BER<10-12; 231 – 1 PRBS.

3. Valid between 1260 and 1355 nm. Per IEEE 802.3ae.

Pin Defintion And Functions

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.

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
