DESCRIPTION This data sheet describes the Infineon Fast Ethernet/FDDI/ATM transceiver--part of Infineon 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 (LCFPMD) 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 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 500 m (fiber-to-the-desk) as compared 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 Infineon multimode transceiver is a single unit comprised of a transmitter, a receiver, and an SC 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 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.

TECHNICAL DATA The electro-optical characteristics described in the following tables are valid only for use under the recommended operating conditions. Recommended Operating Conditions

Parameter Ambient Temperature Power Supply Voltage Supply Current 3.3 V Supply Current 5 V(1) Transmitter Data Input High Voltage Data Input Low Voltage Threshold Voltage Input Data Rise/Fall, 20%80% Data High Time(2) Receiver Output Current Input Duty Cycle Distortion Input Data Dependent Jitter Input Random Jitter Input Center Wavelength Electrical Output Load(3)

Notes 1. For VCCVEE (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 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.

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. 6. Measured at an average optical power level of 20 dBm. 7. Measured at 33 dBm average power. 8. 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. 9. 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. 10. PECL compatible. Load is 50 into VCC 2 V. Measured under DC conditions. For dynamic measurements a tolerance 50 mV should be added for VCC=5 V.
