SPFEIM100_G
Fiber Optic Transceiver For Fast Ethernet
Data Sheet
Description
Features
The 8-pin Optical Transceiver is a highly integrated CMOS
IC combined with a high speed photodiode and LED
designed to receive and transmit up to 125Mbit/s optical
data which can be 4b5b or 8b10b coded (up to 125Mbit/
s). The internal peaking and clamping circuit will yield an
ideal eye-opening.
The Avago high speed fiber optical transceiver for Fast
Ethernet is an excellent solution for converting high
speed binary data to differential digital data.
Application
• Operating temperature range 0°C to 70°C
Optical Transceiver for Fast Ethernet over POF
• Data rate up to 100Mbit/s (125MBaud)
• Integrated EMI shielding
• Operating @ 3.3V Power Supply
• Bare fiber header (which supports thin and flexible Plastic
Optical Fiber (POF) with 1.5mm outer jacket diameter)
integrated. Fiber pull out strength >20N (Ta = 25°C)
• Green package (lead free and halogen free)
• 650nm LED with integrated driving circuit (logic to
light)
• No light toggling of the LED at no signals on the input
data lines
Safety Hints
Applications of new chip technologies lead to increasing optical efficiency and growing and higher
levels of optical performance. We therefore recommend that the current versions of the IEC 60825-1 and
EN 60825-1 standards are taken into account right from the outset, i.e. at the equipment development stage, and
that suitable protection facilities are provided.

Notes:
1. The output power coupled into plastic fiber PIN is measured with a large area detector at the end of a short length of fiber (about 2m). The 2m
long POF is being used in order not the measure the power in the leaky modes (optical power not guided in a long fiber).
2. The temperature coefficient PIN is described between +20°C and 70°C by using a linear coefficient
3. Defined by design (reviewed by monitoring, qualification and/ or characterisation). Not subject to production test
4. For Receiver defined by design (reviewed by monitoring, qualification and/ or characterisation). Not subject to production test
5. Tested with one fixed parameter
6. Max. testing data rate = 100Mbps; 125Mbps are defined by design (reviewed by characterisation and qualification)
7. In case of rework max. 1 time repair soldering is permitted (for more details see Application information).
8. Moisture sensitivity classification is MSL4 according to JEDEC J-STD-020C (for more details see Application information).
9. System test on reference board with INFINEON NINJA switch IC using clock recovery, random pattern and 100 Mbps net data rate.

Note:
Shown is the minimum external circuitry at DC-coupling for the connection of the optical receiver to a FE-PHY. DC-coupling would be possible, if the
common mode voltage and voltage swing at the data lines are within the recommended values (see electrical characteristics, parameters).
