Lantiq adds HD voice support to 2.4 GHz cordless phones silicon

Lantiq (www.lantiq.com) has added CAT-iq-like support to its latest 2.4 GHz chipset, including wideband voice.

The new COSIC™ WDCT chipset is targeted for inclusion into cordless handsets to be sold in Asia-Pacific countries and emerging markets that use 2.4 GHz.

Support for G.722 is included for both encoding and transmission, along with “advanced” acoustic cancellation to support “brilliant” HD voice quality for conversation and recording, including full duplex hands free operation.

Other features being touted are low-data rate services, high signal-to-noise ratio, and adaptive collision detection and channel selection for co-existence with 2.4 GHz WANs.

Samples are available now to qualified customers, with volume production beginning in 1Q 2012.  There is also an available reference design for a basestation/handset combination, including hardware and core firmware.  The solution is also supported for integration into broadband home gateways.
