850nm Optical Video Dual Receiver
TRMV3GCR2x000E2G
Pb
Product Description
The TRMV3GCR2x000E2G is a dual channel optical receiver module
engineered for exceptional performance with SDI pathological patterns.
The receivers feature best-in-class optical receive sensitivity for SMPTE
259M, SMPTE 344M, SMPTE 292M and SMPTE 424M serial rates, thus
providing superior optical link budget and robustness.
The receivers exceed the SMPTE 297-2006 specifications and are designed to
provide error-free reception of signals from 50Mbps to 3Gbps. The receivers
connect to a standard 20-pad SFP connector for hot plug capability. This
allows the system designer to make configuration changes or maintenance
by simply plugging in different transceivers without removing the power
supply from the host system
The TRMV3GCR2x000E2G provides extensive operational status monitoring
through an I2C interface. All DDM functions are offered including receiver
input optical power, power supply and operating temperature. If a
monitored parameter falls outside the pre-defined range, an alarm or
warning 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.
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.
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.
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.
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 I2C 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,

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.
