D E S C R IP T IO N :
The IDT7M9230/31/32/40/41/42 provides reliable, high performance Asynchronous Transfer Mode connectivity with Available Bit Rate (ABR) support for PCI Mezzanine Card (PMC)-based systems. The IDT7M9230/ 31/32/40/41/42 is designed for mechanical and electrical compliance with the Common Mezzanine Card Specification (IEEE1386) and the PCI Mezzanine Card Specification (IEEE1386.1). This low-profile I/O card is ideally suited to serve as an ATM Uplink on a Fast Ethernet switch or as ATM I/O card mounted on a standard VME or Compact PCI Single Board Computer.
OVERVIEW:
The central component of the IDT7M9230/31/32/40/41/42 is the IDT77252ABR NICSTARTM Segmentation and Reassembly (SAR) controller. The IDT77252ABR SAR connects directly to the PCI bus, a private SRAM/EPROM bus, and the Utopia PHY interface. The IDT77252ABR's PCI bus master interface provides efficient, low latency DMA transfer capability over PCI. For further information on the IDT77252ABR refer to the IDT77252ABR Datasheet located on the IDT website (www.idt.com). The IDT77155 PHY chip provides the SONET/SDH processing and ATM mapping functions of a 155Mbps ATM User Network Interface. The IDT77155 provides both Transmission Convergence (TC) and Physical Media Dependent (PMD) sublayer functions and supports a UTOPIA interface. For further information on the IDT77155 refer to the IDT77155 Datasheet located on the IDT website(www.idt.com).
