Single Fiber Bi-Directional Gigabit Ethernet
SFP Transceivers with Digital Diagnostics
TRPBG1LX
Pb
Product Description
The TRPBG1LX modules are single fiber, bi-directional SFP transceivers
that provide a quick and reliable interface for 1000BASE-BX10-D/U Gigabit
Ethernet applications. Two types of modules are available: the 1310nm
Fabry Perot laser-based transceiver (BX10-U) and the 1490nm DFB laserbased transceiver (BX10-D). The transceivers are integrated with digital
diagnostics monitoring, which provides features to detect a problem
before system performance is impacted. The diagnostic functions, alarms
and warning features are provided via an I2C serial interface as described
per the Multi-Source Agreement (MSA) document, SFF-8472 (Rev. 9.4).
All modules meet Class I Laser Safety requirements in accordance with
the U.S. and international standards as described in the FDA/CDRH and
IEC-60825 documents, respectively. The TRPBG1LX transceivers connect
to standard 20-pad SFP connectors for hot plug capability.
Features
 Compatible with SFP MSA
This allows the system designer to make configuration or maintenance
changes by simply plugging in different types of transceivers without
removing the power supply from the host system.
 Compliant with IEEE 802.3ah Draft 3.3 Gigabit
Ethernet 1000BASE-BX10 PMD Specifications
The transceivers have color-coded latches that identify the TX wavelength.
The MSA compliant latch offers an easy and convenient way to release the
module.
 Digital Diagnostics through Serial Interface
The transmitter and receiver DATA interfaces are AC-coupled internally. LVTTL Transmitter Disable control input and Loss of Signal output interfaces
are also provided.
 Eye Safe (Class I Laser Safety)
The transceivers operate from a single +3.3V power supply over an
operating case temperature range of -5°C to +70°C or -40°C to +85°C. The
package is made of metal.

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
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 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 startand
end of serial protocol activation. The supported monitoring
functions are internal temperature, supply 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
that should be pulled up with a 4.7 - 10kΩ resistor on the
host board. TX Fault is latched per SFP MSA.
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).
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.
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).
