Product Description
The TRPV3GELRx000M2G is an optical transceiver module designed to
transmit and receive electrical and optical serial digital signals as defined
in SMPTE 297-2006. The TRPV3GELRx000M2G is specifically designed for
robust performance in the presence of SDI pathological patterns for SMPTE
259M, SMPTE 344M, SMPTE 292M and SMPTE 424M serial rates.
The TRPV3GELRx000M2G contains a PIN photodiode receiver and a 1310nm
Fabry-Perot laser transmitter designed to provide error-free transmission of
signals from 50Mbps to 3Gbps over single mode fiber (9/125). It is also hot-
pluggable.
The TRPV3GELRx000M2G provides extensive operational status monitoring
through an I
2
C interface. Input optical power is monitored in the receiver;
output optical power and bias current are monitored in the transmitter.
Other operating conditions, such as power supply and operating
temperature are also monitored. If a monitored parameter falls outside the
pre-defined range, an alarm flag for the parameter is raised

Application Notes
Electrical Interface:
Signal interfaces are compatible with
the SFP MSA specification. The high speed DATA interface
is differential AC-coupled internally 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 logic HIGH
when an insufficient photocurrent is produced.
Serial Identification and Monitoring:
The module definition
of SFP is indicated by the MOD_ABS pin and the 2-wrie serial
interface. Upon power up, the 2-wrie interface appears as NC
(no connection), and MOD_ABS 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 device that are not write protected,
and the negative edge clocks data from the device. The serial
data signal (SDA) is for serial data transfer. The host uses SDA
in conjunction with SCL to mark the start and end of serial
protocol activation. The supported monitoring functions
are temperature, voltage, average receiver signal, all alarms
and warnings, and software monitoring of 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 SFP MSA,
and SFF-8472, Rev. 9.4.
Power Supply and Grounding:
The power supply line should
be well-filtered. All power supply bypass capacitors should be
as close to the transceiver module as possible.
Laser Safety:
All transceivers are Class I Laser products per
FDA/CDRH and IEC-60825 standards. They
must be operated under specified operating
conditions.
