RSP12SEX complies with Gigabit Ethernet as specified in IEEE 802.3 and Fiber Channel FC-PI 13.0. Digital diagnostics functions are available via the 2-wire serial bus specified in the SFF-8472 rev.10.4. The transmitter part has 1310 nm DFB laser and back facet monitor. The receiver part has an InGaAs PIN-PD and a preamplifier. 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. 1 Rev.

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 4.7k ~ 10k 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 4.7k ~ 10k. 4. MOD-DEF 0, 1, 2 are the SFP module definition pins. They should be pulled up with a 4.7k ~ 10k 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 RSP12SEX SFP transceivers operate at 1x Fiber Channel, Gigabit Ethernet, and respective protocols without active control. 6. LOS is an open collector output. Shall be pulled up with a 4.7k ~ 10k on host board. Pull up voltage between 2.0 and VccR+0.3. Logic 0 indicates normal operation. 4 Rev.
