GERERAL OPERATING CHARACTERISTICS

ELECTRICAL INPUT/OUTPUT CHARACTERISTICS

 Receiver

Note 1) TD+/- are internally AC coupled with 100Ω 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 10kΩ 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 100Ω (differential) at the user SERDES.

OPTICAL CHARACTERISTICS

 Receiver (0~70℃@10.3125Gb/s)

Note 1) Class 1 Laser Safety per FDA/CDRH and IEC-825-1 regulations.

Note 2) 20%~80%

Note 3) Measured with a PRBS 231-1 test pattern, @6.25Gb/s, BER<10-12

SERIAL INTERFACE FOR ID AND DDM

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 Table 1.

Detailed ID information(A0h) is listed in Ta-ble 2. And the DDM specification(A2h) is described

in Table 3. 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.

PIN DEFINITIONS AND FUNCTIONS

Note 1) The module ground pins shall be isolated from the module case.

Note 2) This pin is an open collector/drain output pin and shall be pulled up with

4.7K-10Kohms to Host_Vcc on the host board.

Note 3) This pin shall be pulled up with 4.7K-10Kohms to VccT in the module.

Note 4) This pin is an open collector/drain output pin and shall be pulled up with

4.7K-10Kohms to Host_Vcc on the host board. In FC designated as RX_LOS, inSONET

designated as LOS, and in Ethernet designated at Signal Detect.

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
