TRCE03KE2C000C3

OC-3 1510nm Optical Supervisory
Channel SFP Transceiver
TRCE03KE2C000C3
Product Description
The TRCE03KE2C000C3 SFP fiber optic transceiver with integrated
digital diagnostics monitoring functionality provides 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 I2C serial interface.
The TRCE03KE2C000C3 transceiver uses a 1510nm 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 transceiver connects 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.
Features
 1510nm DFB Transmitter and APD Receiver
The transceiver has a blue bail-type latch, which offers an easy
and convenient way to release the module. The latch is compliant
with the SFP MSA.

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
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.
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.
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.
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 I2C serial interface) and generates the serial clock
signal (SCL). The positive edge clocks data into the EEPROM
