Note:

1. SDA,SCL,MOD-ABS. These are the module definition pins. They should be pulled up with a 4.7~10K resistor on the host board

to supply less than VccT+0.3V or VccR+0.3V.

MOD-ABS is grounded by the module to indicate that the module is present.

SCL is clock line of two wire serial interface for optional serial ID.

SDA is data line of two wire serial interface for optional serial ID.

2. LOS (Loss of signal) is an open collector output, which should be pulled up with a 4.7k~10kΩ resistor on the host board to a

voltage between 2.0V and Vcc+0.3V. Logic 0 indicates normal operation; logic 1 indicates loss of signal. In the low state, the output will be pulled to less than 0.8V.

4. 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 thus not required on the host board.

5. These are the differential transmitter inputs. They are AC-coupled, differential lines with 100Ω differential termination inside

the module.

Digital Diagnostic Memory Map

The SFP series defines a 256-byte memory map in EEPROM describing the transceiver’s capabilities, standard interfaces, manufacturer, and other information, which is accessible over a 2 wire serial interface at the 8-bit address 1010000X (A0h),see Figure. The memory contents refer to SFF-8472 Rev 9.5. A2 EEPROM Definition Specific settings please consult our engineer.
