Multi-rate Gigabit Ethernet & Fibre Channel
SFP Transceivers with Digital DiaGnostics
TRPCG1-E2G Single Mode
Product Description
The TRPCG1-E2G SFP series of multi-rate fiber optic transceivers with
integrated digital diagnostics monitoring functionality provide a quick
and reliable interface for 1000BASE-LX Gigabit Ethernet and 1.062GBd
Fibre Channel applications. The transceivers are designed to support
data rates ranging from 1.25Gb/s down to 125Mb/s. 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
I
2
C serial interface.
The transceivers use a 1310nm Fabry Perot laser and provides a
minimum optical link budget of 11dB, corresponding to a minimum
distance of 10km, assuming fiber loss of 0.45dB/km. All 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 host
system.
The transceivers have colored bail-type latches, which offer an easy
and convenient way to release the modules. The latch is compliant
with the SFP MSA.
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
operating case temperature ranges of -5°C to +70°C (Commercial)
or -40°C to +85°C (Industrial). The housing 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 deasserts 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)
Laser Safety
Laser Safety:
All transceivers are Class I Laser products per FDA/
CDRH and IEC-60825 standards. They must be operated under
specified operating conditions.
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
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.
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.
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.
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.
