V23809-C8-C10

This data sheet describes the Infineon Fast Ethernet/FDDI/ATM transceiver-part of Infineon Multistandard Transceiver Family. V23809-C8-C10 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).

V23809-C8-C10 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. V23809-C8-C10 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 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 of V23809-C8-C10 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.
