1.11 CNR

The CNR connector provides an interface that supports the audio, modem, and LAN interfaces of
the Intel 845G chipset
•
AC '97 interface: supports audio and/or modem functions on the CNR card.
•
LAN interfaces: supports Platform LAN Connection (PLC) based devices through an eight-
pin interface
•
SMBus interface: provides Plug-and-Play functionality for the CNR card.
The CNR connector includes power signals required for power management and for CNR card
operation. To learn more about the CNR, refer to the CNR specification.
The onboard two-channel audio subsystem can be upgraded to four- or six-channel audio using a
CNR audio upgrade card in a slave configuration. CNR audio upgrade cards are available in
multiple configurations from several vendors supporting analog or S/P-DIF digital connections.

INTEGRATOR'S NOTES
•
If you install a CNR card that cannot support a multichannel audio upgrade, the Desktop
Boards' integrated audio codec will be disabled. This only applies to Desktop Boards that
have both the onboard audio subsystem and a CNR connected.
•
The brand and type of audio codec used on the CNR card must match that of the Desktop
Boards' codec (Analog Devices AD1981A).
•
Check with your CNR vendor to ensure that the CNR card has been tested with ICH4-
based systems.
•
There is no USB interface routed to the CNR connector.
