TRPEG1EEXC000E2

Multi-rate Gigabit Ethernet & Fibre Channel
SFP Transceivers with Digital DiaGnostics
TRPEG1-E2 Single Mode
Produ c t D es c rip tion
The TRPEG 1-E2 SFP series of multi-rate fiber optic transceivers w ith
integrated digital diagnostics monitoring functionality provide a quick
and reliable interface for 1000BA SE-LX G igabit Ethernet and 1.062G Bd
Fibre Channel applications. The transceivers are designed to support
data rates ranging from 1.25G b/s dow n to 125M b/s. The diagnostic
functions,alarm and w arning features as described in the M ulti-Source
A greement (M SA ) document,SFF-8472 (Rev. 9.4),are provided via an I2C
serial interface.
Four options are offered w ith minimum optical link pow er budgets of11dB,
18dB,22dB and 24dB to support 10km to 80km link applications. Option
“LX” uses 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. Option “EX” uses a 1310nm D FB laser
and provides a minimum optical link budget of 18dB,corresponding to
a minimum distance of40km,assuming fiber loss of0.35dB/km. Options
“YX”and “ZX”use 1550nm D FB lasers and provide a minimum optical link
budgets of 22dB and 24dB respectively,w hich correspond to minimum
distances of 70km and 80km, assuming fiber loss of 0.25dB/km. A ll
modules satisfy Class I Laser Safety requirements in accordance w ith the
U .S. FD A /CD RH and international IEC-60825 standards.
The transceivers connect to standard 20-pad SFP connectors for hot plug
capability. This allow s the system designer to make configuration changes
or maintenance by simply plugging in different types of transceivers
w ithout removing the pow er supply from the host system.
The transceivers have colored bail-type latches,w hich offer an easy and
convenient w ay to release the modules. The latch is compliant w ith the
SFP M SA .
The transmitter and receiver D ATA interfaces are AC-coupled internally.
LV-TTL Transmitter D isable control input and Loss of Signal output
interfaces are also provided.
The transceivers operate from a single +3.3V pow er supply over operating
case temperature ranges of-5°C to +70°C or -40°C to +85°C. The housing
is made ofmetal for EM I immunity.

A pplication N otes
Electrical Interface: A ll signal interfaces are compliant w ith
the SFP M SA specifi cation. The high speed D ATA interface
is diff erential A C-coupled internally w ith 0.1µF and can be
directly connected to a 3.3V SERD ES IC. A ll low speed control
and sense output signals are open collector TTL compatible
and should be pulled up w ith a 4.7 - 10kΩ resistor on the host
board.
up, M OD _D EF(1:2) appear as N C (no connection), and
M OD _D EF(0) is TTL LOW . W hen the host system detects this
condition,it activates the serial protocol (standard tw o-w ire
I2C serial interface)and generates the serial clock signal (SCL).
The positive edge clocks data into the EEPROM segments of
the SFP that are not w rite protected,and the negative edge
clocks data from the SFP.
Loss of Signal (LOS): The Loss of Signal circuit monitors the
level ofthe incoming optical signal and generates a logic H IG H
w hen an insufficient photocurrent is produced.
The serial data signal (SD A ) is for serial data transfer. The
host uses SD A in conjunction w ith SCL to mark the start and
end of serial protocol activation. The supported monitoring
functions are temperature,voltage,bias current,transmitter
pow er,average receiver signal,all alarms and w arnings,and
softw are monitoring ofTX Fault/LOS. The device is internally
calibrated.
TX Fault: The output indicates LOW w hen the transmitter
is operating normally,and H IG H w ith a laser fault including
laser end-of-life. TX Fault is an open collector/drain output
and should be pulled up w ith a 4.7 - 10kΩ resistor on the host
board. TX Fault is non-latching (automatically deasserts w hen
fault goes aw ay).
The data transfer protocol and the details of the mandatory
and vendor specific data structures are defined in the SFP M SA ,
and SFF-8472,Rev. 9.4.
TX Disable: W hen the TX D isable pin is at logic H IG H , the
transmitter optical output is disabled (less than -45dBm).
Power Supply and Grounding: The pow er supply line should
be w ell-filtered. A ll 0.1μF pow er supply bypass capacitors
should be as close to the transceiver module as possible.
Serial Identification and Monitoring: The module definition
of SFP is indicated by the three module definition pins,
M OD _D EF(0), M OD _D EF(1) and M OD _D EF(2). U pon pow er
