with Digital Diagnostics
TRPU12xxxx000E2G
Pb
Product Description
The TRPC12-E2G SM SFP series of multi-rate fiber optic transceivers with
integrated digital diagnostics monitoring functionality provide a quick
and reliable interface for OC-12 short reach (SR), intermediate reach (IR)
and long reach (LR) applications. 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.
Available products under this series are compliant with SONET/SDH
standards for OC-12/STM-4 applications and are capable of operating
down to 155Mb/s data rate. The SR-1 and IR-1 versions are compliant
with OC-12/STM-4 and OC-3/STM-1 interface standards. All modules
satisfy Class 1 Laser Safety requirements in accordance with the U.S. and
international standards as described in the FDA/CDRH and IEC-60825
documents, respectively.
The TRPC12-E2G 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 shutting down 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 design incorporates a highly reliable 1310nm or 1550nm
InGaAsP laser and an integrated driver circuit. The receiver features a
transimpedance amplifier IC optimized for high sensitivity and wide
dynamic range. The transmitter and receiver DATA interfaces are AC-
coupled internally. LVTTL Transmitter Disable control input and Loss of
Signal output interfaces are also provided.
The transceivers operate from a single +3.3V power supply over operating
case temperature ranges of -5°C to +70°C (COM), -40°C to +85°C (IND) or
-5°C to +85°C (EXT). 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.
