LC Gigabit 80km 1490/1570nm SFP
Transceiver w/ Digital Diagnostics
TRBCG1HxZx000E1G
Product Description
The TRBCG1HKZx000E1G and TRBCG1HMZx000E1G 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 1570nm 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 I
2
C 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 TRBCG1HKZx000E1G and TRBCG1HMZx000E1G 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.
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.
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 de-asserts when
fault goes away).
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) 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 I
2
C serial interface) and generates the serial clock signal
(SCL). The negative edge clocks data from the SFP EEPROM.
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 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.
