Mul
ti-rate Gigabit Ethernet & Fibre Channel SFP
CWDM Transceivers with Digital Diagnostics
TRP1G1xxXIxG CWDM
Product Description
The TRP1G1xxXIxG SFP series of multi-rate fiber optic transceiv-
ers with integrated digital diagnostics monitoring functional-
ity provide a quick and reliable interface for 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. Diagnostics monitoring functionality (alarm and warn-
ing features) is integrated into the design via an I
2
C serial inter-
face per the Multi-Source Agreement (MSA) SFF-8472, Rev. 9.4.
There are eight center wavelengths available: 1471nm, 1491nm,
1511nm, 1531nm, 1551nm, 1571nm, 1591nm and 1611nm. Three
optical link power budget options are offered, YX (22dB mini-
mum), ZX (24dB minimum) and VX (32dB minimum). They cor-
respond to transmission distances of 62km, 70km and 120km,
respectively (assuming a total connector/splice/CWDM mux and
demux loss of 4.5dB, allocated system penalty of 2dB and fiber
loss of 0.25dB/km). All modules satisfy Class I Laser Safety require-
ments in accordance with the U.S. FDA/CDRH and international
IEC-60825 standards.
The TRP1G1xxXIxG CWDM transceivers connect to standard 20-
pad SFP connectors for hot plug capability. This allows the system
designer to make configuration changes or maintenance by sim-
ply 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 in-
ternally. LV-TTL Transmitter Disable control input and Loss of Sig-
nal output interfaces are also provided.
The transceivers operate from a single +3.3V power supply over
an operating temperature range of -40°C to +85°C (-40°C to 0°C is
ambient, and 0°C to +85°C is case). 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 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.
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 -35dBm,
-45dBm for F7G). Optical output is disabled from cold start
until operating wavelength is within specified range.
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 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.
Laser Safety:
All transceivers are Class I Laser products per
FDA/CDRH and IEC-60825 standards. They must be operated
under specified operating conditions.
