The TNETA1585 is an asynchronous transfer mode (ATM) programmable traffic management scheduler device that is used with a segmentation and reassembly (SAR) device to provide a flexible, high-performance solution for the available bit rate (ABR) service category. Its programmability enables it to support other special modes including variable-bit-rate non-real-time (VBR-nrt) service category and virtual-path (VP)-level ABR in addition to and simultaneously with ABR. Combining the TNETA1585 with the TNETA1575 provides a high-performance solution for classical LAN-to-ATM backbone applications, including high-performance networking hubs. This data sheet provides information on the device hardware specifications that includes device interfaces, timing diagrams, electrical characteristics, terminal and package information, and an overview of device operation. All information on the TNETA1585 data structures, configuration, and features is provided in the TNETA1585 Programmer's Reference Guide, literature number SDNU016. Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of Texas Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet.
