82NM10 Datasheet, PDF (42/671 Pages) Intel Corporation – Intel® NM10 Family Express Chipset

Introduction
Note:
Chipset’s SMBus also implements hardware-based Packet Error Checking for data
robustness and the Address Resolution Protocol (ARP) to dynamically provide address
to all SMBus devices.
Intel® HD Audio Controller (Intel® HD Audio)
The Intel HD Audio Specification defines a digital interface that can be used to attach
different types of codecs, such as audio and modem codecs. In this chipset Intel HD
Audio digital link shares pins with the AC-link. Chipset’s Intel HD Audio controller
supports up to three codecs.
With the support of multi-channel audio stream, 32-bit sample depth, and sample rate
up to 192 kHz, the Intel HD Audio controller provides audio quality that can deliver CE
levels of audio experience. On the input side, chipset adds support for an arrays of
microphones.
The Intel HD Audio controller uses multi-purpose DMA engines, to effectively manage
the link bandwidth and support simultaneous independent streams on the link. The
capability enables new exciting usage models with Intel HD Audio (e.g., listening to
music while playing multi-player game on the internet.) The Intel HD Audio controller
also supports isochronous data transfers allowing glitch-free audio to the system.
Users interested in providing feedback on the Intel High Definition Audio Specification
or planning to implement the Intel High Definition Audio Specification into a future
product will need to execute the Intel High Definition Audio Specification Developer’s
Agreement. For more information, contact [e-mail].
