UPD98401A - ATM SAR CHIP

Datasheet Summary

Description

The µPD98401A (NEASCOT-S15TM) is a high-performance SAR chip that segments and reassembles ATM cells.

This chip can interface with an ATM network when it is included in a workstation, computer, front-end processor, network hub, or router.

Features

  • Conforms to ATM Forum.
  • AAL-5 SAR sublayer and ATM layer functions.
  • Hardware support of AAL-5 processing.
  • Processing of non-AAL-5 traffic (AAL-3/4 cell, OAM cell, RM cell) by software with raw cell processing function.
  • Hardware support of comparison/generation of CRC-10 for non-AAL-5 traffic.
  • Supports up to 32K virtual channels (VC).
  • Provided with 16 traffic shapers that carry out transmission scheduling (control of average rate/peak.
