Multi-rate Gigabit Ethernet & FibreChannel SFP
CWDM Transceivers with Digital Diagnostics
TRPEG1-G MR CWDM
Pb
Product Description
The TRPEG1-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 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 warning features) is integrated into
the design via an I
2
C serial interface per the Multi-Source Agreement (MSA)
SFF-8472, Rev. 9.4.
There are eighteen center wavelengths available, from 1271nm to 1611nm.
Two optical link power budget options are offered, YX (22dB minimum)
and ZX (24dB minimum). They correspond to transmission distances of
62km and 70km 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 requirements in
accordance with the U.S. FDA/CDRH and international IEC-60825 standards.
The TRPEG1-G MR 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 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
that should be pulled up with a 4.7 - 10kΩ resistor on the host
board. TX Fault is latched per SFP MSA.
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 startand
end of serial protocol activation. The supported monitoring
functions are internal temperature, supply 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 SFPMSA,
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.
