DESCRIPTION This data sheet describes the Siemens Fast Ethernet/FDDI/ATM transceiver--part of Siemens Multistandard Transceiver Family. It is fully compliant with the Asynchronous Transfer Mode (ATM) OC-3 standard, the Fiber Distributed Data Interface (FDDI) Low Cost Fiber Physical Layer Medium Dependent (LCF-PMD) draft standard(1), and the FDDI PMD standard(2). ATM was developed because of the need for multimedia applications, including real time transmission. The data rate is scalable and the ATM protocol is the basis of the broadband public networks being standardized in the International Telegraph and Telephone Consultative Committee (CCITT). ATM can also be used in local private applications. FDDI is a Dual Token Ring standard developed in the U.S. by the Accredited National Standards Committee (ANSC) X3T9, within the Technical Committee X3T9.5. It is applied to the local area networks of stations, transferring data at 100 Mbits/s with a 125 MBaud transmission rate. LCF FDDI is specially developed for short distance applications of up to 500 m (fiber-to-the-desk) as compared to 2 km for backbone applications. Fast Ethernet was developed because of the higher bandwidth requirement in local area networking. It is based on the proven effectiveness of millions of installed Ethernet systems. The Siemens multimode transceiver is a single unit comprised of a transmitter, a receiver, and an ST receptacle. This design frees the customer from many alignment and PC board layout concerns. The modules are designed for low cost applications. The inputs/outputs are PECL compatible and the unit operates from a 3.0 V to 5.5 V power supply. As an option, the data output stages can be switched to static levels during absence of light, as indicated by the Signal Detect function. It can be directly interfaced with available chipsets.

Notes 1. For VCC-VEE (min., max.). 50% duty cycle. The supply current (ICC2+ICC3) does not include the load drive current (Icc1). Add max. 45 mA for the three outputs. Load is 50 into VCC -2V. 2. To maintain good LED reliability, the device should not be held in the ON state for more than the specified time. Normal operation should be done with 50% duty cycle. 3. To achieve proper PECL output levels the 50 termination should be done to VCC -2 V. For correct termination see the application notes.

Notes 1. Measured at the end of 5 meters of 62.5/125/0.275 graded index fiber using calibrated power meter and a precision test ferrule. Cladding modes are removed. Values valid for EOL and worst-case temperature. 2. The input data pattern is a 12.5 MHz square wave pattern. 3. Center wavelength is defined as the midpoint between the two 50% levels of the optical spectrum of the LED. 4. Spectral width (full width, half max) is defined as the difference between 50% levels of the optical spectrum of the LED. 5. 10% to 90% levels. Measured using the 12.5 MHz square wave pattern with an optoelectronic measurement system (detector and oscilloscope) having 3 dB bandwidth ranging from less than 0.1 MHz to more than 750 MHz. 6. Extinction Ratio is defined as PL/PH x 100%. Measurement system as in Note 5. 7 Optical Power Low is the output power level when a steady state . low data pattern (FDDI Quiet Line state) is used to drive the transmitter. Value valid <1 ms after input low. 8. Test method as for FDDI-PMD. Jitter values are peak-to-peak. 9. Duty Cycle Distortion is defined as 0.5 [(width of wider state) minus (width of narrower state)]. It is measured with stream of Idle Symbols (62.5 MHz square wave). 10.Measured with the same pattern as for FDDI-PMD. 11. Measured with the Halt Line state (12.5 MHz square wave).

Notes 1. For a bit error rate (BER) of less than 1x10E-12 over a receiver eye opening of least 1.5 ns. Measured with a 223-1 PRBS at 155 MBd. 2. For a BER of less than 1x10E-12. Measured in the center of the eye opening with a 223-1 PRBS at 155 MBd. 3. Measured at an average optical power level of -20 dBm with a 62.5 MHz square wave. 4. All jitter values are peak-to-peak. RX output jitter requirements are not considered in the ATM standard draft. In general the same requirements as for FDDI are met. 5. Measured at an average optical power level of -20 dBm. 6. Measured at -33 dBm average power. 7 An increase in optical power through the specified level will . cause the SIGNAL detect output to switch from a Low state to a High state. 8. A decrease in optical power through the specified level will cause the SIGNAL detect output to switch from a High state to a Low state. 9. PECL compatible. Load is 50 into VCC -2 V. Measured under DC conditions. For dynamic measurements a tolerance of 50 mV should be added for VCC=5 V.
