Fast Ethernet 100BASE-LX10 SFP
Transceivers with Digital Diagnostics
TRXAFEEX/ZX
Product Description
The TRXAFEEX/ZX SFP fiber optic transceivers provide a quick and reliable
interface for 100BASE-LX10 Fast Ethernet single mode applications. The
transceivers are compliant with IEEE802.3ah/D3.3 standard. The diagnostic functions, alarm and warning features as described in the Multi-Source
Agreement (MSA) document, SFF-8472 (Rev. 9.4), are provided via an I2C
serial interface. All transceiver modules satisfy Class I Laser Safety requirements in accordance with the U.S. FDA/CDRH and international IEC-60825
standards.
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 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 incorporates a highly reliable 1310nm InGaAsP laser
and an integrated driver circuit. The receiver features a transimpedance
amplifier IC optimized for high sensitivity and wide dynamic range. The
transmitter and receiver DATA interfaces are AC-coupled internally. LVTTL Transmitter Disable control input and Loss of Signal (LOS) output interfaces are also provided.
The transceivers operate from a single +3.3V power supply over operating case temperature range of -5°Cto +70°C (“B” 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 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.
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 I2C serial interface) and
generates the serial clock signal (SCL). The positive edge clocks
data into the EEPROM segments of the SFP that are not write
protected, and the negative edge clocks data from the SFP.
This device does not require clock stretching.
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. The supported monitoring
functions are temperature, voltage, bias current, transmitter
power, average receiver signal, all alarms and warnings, and
software monitoring of TX Fault/LOS. The device is internally
calibrated.
TX Fault: The output indicates LOW when the transmitter
is operating normally, and HIGH with a laser fault including
laser end-of-life. TX Fault is an open collector/drain output
and should be pulled up with a 4.7 - 10kΩ resistor on the host
board. TX Fault is non-latching (automatically deasserts when
fault goes away).
The data transfer protocol and the details of the mandatory
and vendor specific data structures are defined in the SFP MSA,
and SFF-8472, Rev. 9.4.
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)
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.
Laser Safety: All transceivers are Class I Laser products
per FDA/CDRH and IEC-60825 standards. They must be
operated under specified operating conditions.
