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) = 0 to 70 ℃, TOP(I) =-40 to 85 ℃, VCC = 3.13 to 3.47 V)

Notes:

1. TD+/- are internally AC coupled with 100Ω differential termination inside the module.

2. Tx Fault and Rx LOS are open collector outputs, which should be pulled up with 4.7k to 10kΩ resistors on the host board. Pull up voltage between 2.0V and Vcc+0.3V.

3. RD+/- outputs are internally AC coupled, and should be terminated with 100Ω (differential) at the user SERDES.

Optical Characteristics (TOP(C) = 0 to 70 ℃, TOP(I) =-40 to 85 ℃,VCC = 3.13 to 3.47 V)

Notes:

1. Measured at 1.25Gb/s with PRBS 2 2^{23 – 1}NRZ test pattern.

2. Unfiltered, measured with a PRBS2^{23 – 1} test pattern @1.25Gbps

3. Measured at 1.25Gb/s with PRBS 2^{23 – 1} NRZ test pattern for BER < 1×10^-12

Pin Definitions And Functions

Notes:

1. When high, this output indicates a laser fault of some kind. Low indicates normal operation. And should be pulled up with a 4.7 – 10KΩ resistor on the host board.

2. TX disable is an input that is used to shut down the transmitter optical output. It is pulled up within the module with a 4.7 – 10KΩ resistor. Its states are:

Low (0 – 0.8V): Transmitter on               (>0.8, < 2.0V): Undefined

High (2.0V~Vcc+0.3V): Transmitter Disabled   Open: Transmitter Disabled

3. Mod-Def 0,1,2. These are the module definition pins. They should be pulled up with a 4.7K – 10KΩ resistor on the host board. The pull-up voltage shall be between 2.0V~Vcc+0.3V.

Mod-Def 0 has been 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. When high, this output indicates loss of signal (LOS). Low indicates normal operation.

5. RD+/-: These are the differential receiver outputs. They are AC coupled 100Ω differential lines which should be terminated with 100Ω (differential) at the user SERDES. The AC coupling is done inside the module and is thus not required on the host board.

6. TD+/-: These are the differential transmitter inputs. They are AC-coupled, differential lines with 100Ω differential termination inside the module. The AC coupling is done inside the module and is thus not required on the host board.

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

3. Internal/ External Calibration compatible.
