TRBCG1HxZI000E1G

LC Gigabit 80km 1490/1550nm SFP Transceiver
w/ Digital Diagnostics
TRBCG1HxZx000E1G
Product Description
The TRBCG1HNZx000E1G and TRBCG1HSZx000E1G modules are single
fiber, bi-directional SFP transceivers that provide a quick and reliable interface for 1000BASE-BX-D/U Gigabit Ethernet applications.
Two types of modules are available: the 1490nm DFB laser-based transceiver (BX-U) and the 1550nm DFB laser-based transceiver (BX-D). The
transceivers possess option to be 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 TRBCG1HNZx000E1G and TRBCG1HSZx000E1G transceivers connect
to standard 20-pad SFP connectors for hot plug capability. 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.
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.
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 an operating case temperature range of -5°C to +70°C
or -40°C to +85°C. The package is made of 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 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
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 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: 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.
EEPROM ID is per SFF-8472, Rev. 9.4.
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 and Monitoring: The module definition
