Product Description
The TRPE03KE2C000x0G SFP fiber optic transceivers with integrated
digital diagnostics monitoring functionality provide a quick and
reliable interface for optical supervisory channel 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.
The TRPE03KE2C000x0G transceivers use a CWDM DFB laser and an
APD receiver to provide an optical link power budget of 44dB. The
transceiver satisfies Class I Laser Safety requirements in accordance
with the U.S. FDA/CDRH and international IEC-60825 standards.
The transceivers connect to a standard 20-pad connector 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 latch, which offers an easy
and convenient way to release the module. 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 (COM). 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.
