Multi-rate 10-Gigabit XFP Transceivers
with Digital Diagnostics
XGLRRxM
Pb
Product Description
The XGLRRxM XFP multi-rate fiber optic transceivers with digital diagnostics
monitoring functionality provide a quick and reliable interface for short reach
single mode applications. The diagnostic functions, alarm and warning features
as described in the XFP Multi-Source Agreement (MSA) are provided via standard
I2C serial interface. The transceivers are compliant with the XFP Multi-Source
Agreement and are designed to support OC-192, 10GE, FC, and FEC data rates of
10.66Gb/s and 11.09Gb/s.
The transceivers utilize a 1310nm Distributed FeedBack (DFB) laser for reach of up
to 10km over single mode fiber. They satisfy Class I Laser Safety requirements in
accordance with the U.S. FDA/CDRH and international
IEC-60825 standards.
The transceivers connect to standard 30-pad XFP 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 transmitter design incorporates a highly reliable 1310nm AlGaInAs DFB laser
and a driver circuit. The receiver features an InGaAs/InP PIN photodiode and a
transimpedance amplifier IC optimized for high sensitivity and wide dynamic
range. The transmitter and receiver DATA interfaces are AC-coupled Current Mode
Logic (CML). LV-TTL Transmitter Disable control input and Loss of Signal output
interfaces are also provided.
The transceivers operate from +3.3V and +5.0V power supplies over three
operating temperature ranges of -5°C to +70°C for “B” option, -5°C to +85°C for
“E” option, or -40°C to +85°C (-40°C to 0°C is ambient and 0°C to +85°C is case) for
“A” option.

Example of SFP host board schematic
R: 4.7 to 10kΩ
Application Notes
Electrical Interface: All signal interfaces are compliant with
the XFP MSA specification. The high speed DATA interface
is differential AC-coupled internally and can be directly
connected to a 3.3V SERDES IC.
an open collector and must be pulled to Host_Vcc on the
host board.
P_Down/RST: The negative edge of Reset Function signal
initiates a complete module reset. Module Behavior During
P_Down and RST: During execution of a reset (t_init) or
while held in Power Down mode, a module may be unable
to determine the correct value for Mod_NR and RX_LOS.
These outputs as well as all interrupt related flags, except
completion of Reset flag, shall be disregarded by the host.
When the module completes a Reset and is not in Power
Down mode, the module must represent the correct value
of both signals on its outputs before posting a completion
of reset interrupt to the host.
RX_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_Dis: When the TX Disable pin is at logic HIGH, the
transmitter optical output is disabled. (less than -45dBm).
P_Down: The Power Down Function pin, when held High by
the host, places the module in the standby (Low Power) mode
with a maximum power dissipation of 1.5W. This protects
hosts which are not capable of cooling higher power modules
which may be accidentally inserted. The module’s 2-wire serial
interface and all laser safety functions must be fully functional
in this low power mode. During P_Down, the module shall still
support the completion of reset Interrupt, as well as maintain
functionality of the variable power supply.
At no time shall a module cause spurious assertion of the
Interrupt pin. When a host initially applies power to a module
with the P_Down/RST signal asserted, a module comes up in
power down mode. The module shall only assert the Interrupt
signal pin to inform the host it has completed a reset. The
completion of reset flag shall be the only interrupt source
flag set during power down mode. The host is expected to
clear this interrupt before releasing the module from the
power down mode. The transition from power down mode
to normal mode will trigger a reset of the module and result
in a 2nd module reset and a 2nd reset completion interrupt
to the host.
Mod_NR: The Mod_NR is an output pin that when High,
indicates that the module has detected a condition that
renders transmitter and or receiver data invalid, shall consist
of logical OR of the following signals:
• Transmit Signal Conditioner Loss of Lock
• Transmitter Laser Fault
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.
• Receiver Signal Conditioner Loss of Lock
Other conditions deemed valuable to the detection of fault
may be added to the Mod_NR. The Mod_NR output pin is
