New Audio System Processors are Ideal for Digital Audio Networking Applications

Highly Integrated Family Combines CobraNet Interface with Powerful Audio DSP Engine to

Dramatically Reduce Overall Audio System Costs

The new CS4961xx family of ICs integrates

Cirrus Logic’s highly regarded audio digital

signal processor (DSP) with Cirrus Logic’s

is the leading standard for delivering real-time,

uncompressed digital audio over Ethernet

networks. The results are highly optimized

audio system processors that offer dramatic

system cost savings and enhanced audio

processing features for manufacturers of

professional, commercial and consumer

networked-audio products.

The CS4961xx audio system processors, which

include the CS496102, the CS496112 and the

CS496122, reduce system costs because they

allow for the removal of a separate, dedicated

audio DSP on the board design. This 32-bit

fixed-point DSP core features 120 MIPS for

custom programming and these three ICs

provide 2, 8 or 16 simultaneous channels of

audio input and output at up to 96 kHz sample

rates. They also provide multiple 16, 20 or

24-bit audio connections across an Ethernet

network. In fact, two-way audio control and

monitoring is possible at any point along

the network.

Featuring a high-speed parallel host port

interface, the CS4961xx allows optional

connection to a host processor as well as

offering Ethernet-based control, monitoring,

and management via industry standard SNMP.

Firmware can be easily updated over Ethernet

using TFTP or via the host interface. Additional

control and monitoring functions are also pro-

vided by the innovative, built-in asynchronous

and packet-bridge functions.

The ICs are designed to expand the market

for CobraNet-enabled networked digital audio

products such as power amplifiers, mixers,

signal processors, intercom systems, ceiling

speakers, loudspeakers, paging systems, and

high-end networked consumer audio gear.
