SFP Transceivers with Digital Diagnostics

Product Description
The TRPUG1-E2G 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 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. All modules satisfy Class 1
Laser Safety requirements in accordance with the U.S. FDA/CDRH and
international IEC-60825 standards.
The 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 bail-type latches, which offer an easy and
convenient way to release the modules. The latch is compliant with the
SFP MSA. Latches are colored-coded to indicate the different wavelength.
The transmitter and receiver DATA interfaces are AC-coupled internally.
LV-TTL Transmitter Disable control input and Loss of Signal (LOS) output
interfaces are also provided.
The transceivers operate from a single +3.3V power supply over operating
case temperature ranges of -40°C to +85°C (Industrial), -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 0.1μF 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 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 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.
