Fast Ethernet SFP
Multimode Transceivers
TRXNFEMM
Product Description
The TRXNFEMM series of fiber optic transceivers provide a quick and reli-
able interface for 100BASE-FX Fast Ethernet multimode applications.
The transceivers connect to standard 20-pad SFP connectors for hot plug
capability. This allows the system designer to make configuration chang-
es or maintenance by simply plugging in different types of transceivers
without removing the power supply from the host system.
The transceivers have bail-type latches, which offer an easy and conve-
nient way to release the modules. The latch is compliant with the SFP
MSA.
The transmitter design incorporates a highly reliable 1310nm LED and a
driver circuit. The receiver features a low noise transimpedance amplifier
IC for high sensitivity and wide dynamic range. The transmitter and re-
ceiver DATA interfaces are AC-coupled internally. LV-TTL Transmitter Dis-
able control input and Loss of Signal output interfaces are also provided.
The transceivers operate from a single +3.3V power supply over three
operating case temperature ranges of -5°C to +70°C (“B” option), -5°C to
+85°C (“E” option) or -40°C to +85°C (“A” option). The housing is made of
plastic and metal for EMI immunity.
