Introduction

This document is intended to help hardware designers integrate the CobraNetTM interface into an audio system design. It covers the CS18100x, CS18101x, CS18102x, CS49610x, CS49611x, and CS49612x members of the CobraNetTM Silicon Series of devices, where “x” is the ROM version (ROM ID). This document also describes the CM-2 module with schematics, mechanical drawings, etc.

CobraNet is a combination of hardware (the CobraNet interface), network protocol, and firmware. CobraNet operates on a switched Ethernet network and provides the following additional communications services.

? Isochronous (Audio) Data Transport

? Sample Clock Distribution

? Control and Monitoring Data Transport

The CobraNet interface performs synchronous-to-isochronous and isochronous-tosynchronous conversions as well as the data formatting required for transporting real-time digital audio over the network.

The CobraNet interface has provisions for carrying and utilizing control and monitoring data such as Simple Network Management Protocol (SNMP) through the same network connection as the audio. Standard data transport capabilities of Ethernet are shown here as unregulated traffic. Since CobraNet is Ethernet based, in most cases, data communications and CobraNet applications can coexist on the same physical network.
