Functional Diagram

Absolute Maximum Ratings

Note: excess of the maximum absolute ratings can cause permanent damage to the module.

General Operating Conditions

Electrical Input/Output Characteristics



Note 1: TD+/- are internally AC coupled with 100Ohm differential termination inside the module.
Note 2: Tx Fault and Rx LOS are open collector outputs, which should be pulled up with 4.7k to 10kOhm resistors on the host board. Pull up voltage between 2.0V and Vcc+0.3V
Note 3: RD+/- outputs are internally AC coupled, and should be terminated with 100Ohm (differential) at the user SERDES.

Optical Characteristics

Receiver (0~70?C@10.3125Gbps)

Transmitter (0~70?C@10.3125Gbps)

Note 1. Measured at 10.3125b/s with PRBS 2^31 ? 1 NRZ test pattern.
Note 2. 20%~80%
Note 3. Under the ER worst case, measured at 10.3125 Gb/s with PRBS 2^31 ? 1 NRZ test pattern for BER < 1x10^-12

SFP Module Control and Management

The SFP modules implement the 2-wire serial communication protocol as defined in the SFP MSA. The serial ID information of the SFP modules and Digital Diagnostic Monitor parameters can be accessed through the I2C interface at address A0h and A2h. The memory is mapped in following table. The DDM specification(A2h) is described in following tables. For more details of the memory map and byte definitions, please refer to the SFF-8472 (Rev 9.3, Aug. 2002), ?Digital Diagnostic Monitoring Interface for Optical Transceivers?. The DDM parameters have been internally calibrated.

DDM Specification

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 at 3.3V. When the recommended supply filtering circuit 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.
