Product Description
The TRMUG1ESXC000E2G fiber optic transceiver with integrated digital
diagnostics monitoring functionality provides a quick and reliable
interface for 1000BASE-SX Gigabit Ethernet applications. 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.
The module satisfies Class 1 Laser Safety requirements in accordance with
the U.S.FDA/CDRH and international IEC-60825 standards.
The transceiver connects to a 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 transceiver has a bail-type latch, which offers an easy and convenient
way to release the modules. The latch is compliant with the SFP MSA.

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.
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 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.
Loss of Signal (LOS): The Loss of Signal circuit monitors the
level of the incoming optical signal and generates 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 SFP MSA,
and SFF-8472, Rev. 9.3.
TX_Disable: When the TX Disable pin is at logic HIGH, the
transmitter optical output is disabled (less than -45dBm).
Power supply and grounding: Thepower supply line should
be well-filtered. All 0.1µF power supply bypass capacitors
should be as close to the transceiver module as possible.
Serial Identification and Monitoring: The module definition
of SFP is indicated by the three module definition pins,
