Introduction
This applications note is intended to help hardware designers integrate the CobraNet
interface into an audio system design. It covers some of the finer points involved in the
use of either the CS18101 device or CPB-18101-CM-2 (CM-2 module). For more detailed
electrical specifications, timing diagrams, etc. please refer to the appropriate Cirrus Logic
data sheet. Additional information is available from Cirrus Logic at http://www.cirrus.com
and Cirrus Logic’s Professional Audio Division at http://www.peakaudio.com.
Whether your design requires the ease of use and upgradability provided by the
CobraNet CM-2 module or the cost-effective, on-board integration of the CS18101 and
support circuitry within your product design, CobraNet technology provides a powerful,
easy-to-use solution for networked audio.
The CS18101 and CM-2 module provide up to eight audio channels with input and output
at 48kHz or 96kHz sampling and 32-bit resolution.
The 100Base-TX Ethernet interface is fully compliant with the IEEE802.3u standard.
Remote control, monitoring, and management is accomplished through an Ethernet-
based Simple Network Management Protocol (SNMP) agent. This allows the use of
inexpensive category-5 cabling for new installations but the system can even be “piggy-
backed” onto an existing network.
