Multi-rate 10-Gigabit 80km XFP
Transceivers with Digital Diagnostics
TXP3XGHL2x
Pb
Product Description
The TXP3XGHL2x XFP multi-rate fiber optic transceivers with digital diagnostics
monitoring functionality provide a quick and reliable interface for 10Gbps
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 SONET/SDH, 10G Ethernet, 10G Fiber Channel and
FEC data rates from 9.95Gb/s to 11.09Gb/s.
Each transceiver utilizes a 1550nm electro-absorption modulated laser with an
APD receiver to support up to 80km 10G applications. The transceivers 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 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 +1.8V, +3.3V and +5.0V power supplies over a
operating case temperature range of -5°C to +70°C (Commercial), -5°C to +85°C
(Extended), or -40°C to +85°C (Industrial).

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.
be added to the Mod_NR. The Mod_NR output pin is an open
collector and must be pulled to Host_Vcc on the host board.
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.
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.
P_Down/RST: The negative edge of Reset Function signal
initiates a complete module reset.
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
