1 3.1G Fiber Channel SFP Transceivers(20km) RSP31SLE-IT3 Applications 3X Fiber Channel Features Up to 3.1Gb/s 20km single-rate Fiber Channel optical data links Compliant with SFP MSA Digital diagnostic SFF-8472 compliant PIN receiver for 20km Very low jitter Metal package for lower EMI Single power supply voltage : +3.3V Low power dissipation LC duplex connector Operating temperature range: -40 C to 85 C Description OE Solutions Small Form Factor Pluggable (SFP) transceivers are compatible with the Small Form Factor Pluggable 20pin Multi-Source Agreement (MSA). RSP31SLE-IT3 and RSP31SEX-IT3 complies with 3X Fiber Channel requirements. Digital diagnostics functions are available via the 2-wire serial bus specified in the SFF-8472 rev The transmitter features ac-coupled differential data inputs, and an LVTTL for Tx disable input and Tx fault output. The receiver features differential ac-coupled data outputs and LVTTL for LOS (Loss of Signal) output. Circuit ground is internally isolated from frame ground. Pulsecom 1

Circuit ground is internally isolated from frame ground. Tx GND and Rx GND may be internally isolated within the TRx module. 2. Tx Fault is an open collector output that shall be pulled up with a 4.7kΩ ~ 10kΩ on the host board. Pull up voltage between 2.0V and VccT + 0.3V. When high, output indicates a laser fault of some kind. When low, output indicates normal operation. The LD output is not turned off in case of Tx Fault 3. Tx Disable is an input that is used to shut down the transmitter optical output. It is pulled up within the TRx with a 4.7kΩ ~ 10kΩ. 4. MOD-DEF 0, 1, 2 are the SFP module definition pins. They should be pulled up with a 4.7kΩ ~ 10kΩ on the host board. The pull-up voltage shall be VccT. MOD-DEF0 indicates that the module is present. MOD-DEF1 is the clock line of 2-wire serial interface for serial ID MOD-DEF2 is the data line of 2-wire serial interface for serial ID 5. OE Solutions RSP31SLE-IT3 SFP transceivers operate at SONET /SDH data rates, 1x and 2x Fiber Channel, Gigabit Ethernet data rates, and respective protocols without active control. 6. LOS is an open collector output. Shall be pulled up with a 4.7kΩ ~ 10kΩ on host board. Pull up voltage between 2.0 and VccR+0.3. Logic 0 indicates normal operation. 4
