Very Long Haul Multi-rate Gigabit Ethernet SFP
CWDM Transceivers with Digital Diagnostics
TRPEG1KVX-G MR CWDM
Pb
Product Description
The TRPEG1KVX-G MR CWDM 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 Fiber 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 high power DFB laser and an ultra high sensitivity
Avalanche Photodiode (APD) receiver to provide a minimum optical
link power budget of 32dB, corresponding to a minimum transmission
distance of 120km of single mode fiber, assuming a total connector/
splice/CWDM mux and demux loss of 4.6dB, allocated system penalty
of 1dB and fiber loss of 0.22dB/km. There are eighteen (18) wavelengths
available, from 1271nm to 1611nm. All transceivers are Class I Laser
products per U.S. FDA/CDRH and international IEC-60825 standards.
The TRPEG1KVX-G MR CWDM multi-rate 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 an
operating case temperature range of -5°C to +70°C (Commercial) or -5°C
to +85°C (Extended). 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) 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.
