Fast Ethernet SFP
Multimode Transceivers
TRPNFEMM
Product Description
The TRPNFEMM 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.

Application Notes
Electrical Interface:
All signal interfaces are compliant with the SFP
MSA specification. The high speed DATA interface is differential AC-
coupled internally with 0.1μF and can be directly connected to a 3.3V
SERDES IC. All low speed control and sense output signals are open
collector TTL compatible and should be pulled up with a 4.7 - 10kΩ
resistor on the host board.
Loss of Signal (LOS):
The Loss of Signal circuit monitors the level
of the incoming optical signal and generates a logic HIGH when an
insufficient photocurrent is produced.
TX Fault:
Per SFP MSA, pin 2 is TX Fault. This transceiver is LED based
and does not support TX Fault. Pin 2 is internally connected to
transmitter circuit ground (TX GND) to indicate normal operation.
TX Disable:
When the TX Disable pin is at logic HIGH, the transmitter
optical output is disabled (less than -45dBm).
Serial Identification and Monitoring:
The module definition of
SFP is indicated by the three module definition pins, MOD_DEF(0),
MOD_DEF(1) and MOD_DEF(2). Upon power up, MOD_DEF(1:2)
appear as NC (no connection), and MOD_DEF(0) is TTL LOW. When
the host system detects this condition, it activates the serial protocol
(standard two-wire I
2
C serial interface) and generates the serial clock
signal (SCL). The negative edge clocks data from the SFP EEPROM.
The serial data signal (SDA) is for serial data transfer. The host uses
SDA in conjunction with SCL to mark the start and end of serial
protocol activation.
The data transfer protocol and the details of the mandatory and
vendor specific data structures are defined in the SFP MSA.
Power Supply and Grounding:
The power supply line should be
well-filtered. All 0.1μF power supply bypass capacitors should be as
close to the transceiver module as possible.
