TRXNFEMM (RoHS)

Fast Ethernet SFP
Multimode Transceivers
TRXNFEMM
Product Description
The TRXNFEMM series of fiber optic transceivers provide a quick and reliable 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 changes 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 convenient 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 receiver DATA interfaces are AC-coupled internally. LV-TTL Transmitter Disable 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: Electrical interface: All signal interfaces are
compliant with the SFP MSA specification. The high speed DATA
interface is differential AC-coupled internally 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.
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 twowire I2C serial interface) and generates the serial clock signal (SCL).
The negative edge clocks data from the SFP EEPROM.
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.
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.
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.
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.
TX Disable: When the TX Disable pin is at logic HIGH, the transmitter
optical output is disabled (less than -45dBm).
Serial Identification: The module definition of SFP is indicated by
Oplink Communications, Inc.
