2.4 GHz wideband/HD voice quality for cordless phones

October 14, 2011 // By Julien Happich
Lantiq has expanded its family of single-chip solutions for advanced cordless home telephony with the COSIC WDCT, a 2.4 GHz version of the company's widely used DECT solution. The IC supports wideband/HD voice quality and low-rate data application capability (similar to European CAT-iq feature-set) to make the cordless phone a value-added component of a digital home.

Wideband coding and transmission and advanced acoustic echo cancellation results in brilliant HD voice quality for conversation and recording, including full duplex hands free speaking with HD sound. Adaptive collision detection and channel selection enable the co-existence with 2.4 GHz wireless LAN. The chip offers a high signal-to-noise ratio (with a sensitivity of approximately -98 dbm), which reduces the transmit power requirement and achieves better range performance than alternative devices.

All members of the COSIC family integrate baseband controller, RF transceiver and power amplifier on single silicon chip, resulting in lowest system Bill of Material (BOM) cost, optimized manufacturing and logistics, smallest PCB footprint and low power consumption. Samples available now to qualified customers for design, with volume production beginning in the first quarter of 2012.
