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.

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).

Package outline Footprint of Device (unit: mm) Recommended application 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).
