1550nm 40km SFP+ Transceivers
TPP7XGJERxG

Product Description
The TPP7XGJERxG is an enhanced small form factor pluggable (SFP+) fiber
optic transceiver with digital diagnostics monitoring functionality (DDM).
Supporting Ethernet and Fiber Channel standards makes it ideally suited for
10Gbps data-com and storage area network applications. DDM functionality
(alarm and warning features) is integrated into the design via an I2C serial
interface per the Multi-Source Agreement (MSA) SFF-8472, Rev. 11.3.
The transceiver supports data rates ranging from 11.3Gbps down to 8Gbps.
It provides an excellent solution for data transmission at 1550nm over up
to 40km single mode fiber. The low power consumption and excellent EMI
performance enable system design with high port density. The product is
RoHS compliant and is designed and tested in accordance with industry
safety standards. The transceiver is Class 1 Laser product per U.S. FDA/CDRH
and international IEC-60825 standards.
The TPP7XGJERxG transceiver connects 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 transceivers without
removing the power supply from the host system. The transmitter and receiver
DATA interfaces are internally AC-coupled. LV-TTL Transmitter Disable control
input and Loss of Signal (LOS) output interfaces are also provided.
The transceiver has bail-type latch, which offers an easy and convenient way
to release the modules. The latch is compliant with the SFP MSA.
The transceiver operates from a single +3.3V power supply over an operating
case temperature range of -5°C to +70°C (commercial), or -5°C to +85°C
(extended) or -40°C to +85°C (industrial) . 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 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 4.7kΩ - 10kΩ resistor on the host
board.
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, 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, 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 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
and should be pulled up with a 4.7kΩ - 10kΩ resistor on the
host board.
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. 11.3.
TX_Disable: When the TX Disable pin is at logic HIGH,
the transmitter optical output is disabled. The laser is also
disabled if this line is left floating, as it is pulled high inside
the transceiver.
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.
Serial Identification and Monitoring: The module
definition of SFP is indicated by the MOD_ABS pin and the
