Application Scenarios & Design Considerations

155 Mbps ATM SAR Controller With ABR Support for PCI-based Networking Applications

Alternative Part Number

  • PCI9052-G --: PCI bus interface controller with similar PCI-to-local bus bridging function, widely used as a drop-in alternative in legacy PCI designs.
  • AMCC-S5933 --: PCI-to-local bus bridge controller offering comparable PCI interface capabilities for embedded and networking applications.
  • PLX-PEX8112 --: PCI Express to PCI bridge that can replace legacy PCI interface controllers in updated designs with similar host interface functionality.
  • PCI9054-AC50PI --: Higher-performance PCI bus master interface chip in the same PLX PCI90xx family, backward-compatible in many PCI bridge designs and readily sourced.
