Features and Benefits of COSIC WDCT • The first 2.4Ghz frequency cordless solution that supports broadband/HD voice call quality and low-rate data application functions (similar to the European CAT-iqTM feature set) makes cordless phones A value-added component of the digital home.
• Wideband encoding and transmission, and advanced acoustic echo cancellation for extremely high-definition voice quality in calls and recordings, including full-duplex hands-free calling with high-definition sound.
• Coexistence with 2.4GHz WLAN through adaptive collision detection and channel selection.
• High signal-to-noise ratio (sensitivity of approximately -98dbm) reduces transmit power requirements and achieves better range performance than alternative devices.
• All COSIC family members integrate baseband controllers, radio frequency (RF) transceivers and power amplifiers on a single silicon chip, minimizing BOM cost, optimizing manufacturing and logistics, and minimizing PCB footprint and low power consumption.
• The entire family of chips uses a single architecture that leverages the manufacturer's investment in hardware and software design from the 1.9 GHz DECT/CAT-iq standard required for licensing to the 2.4 GHz cordless voice platform without authorization.
Availability • Samples are now available for qualified customers to be designed and mass production begins in the first quarter of 2012.
• Available reference designs for base stations and handsets include hardware and core firmware to support full-duplex hands-free, ring tones and ECO mode (a DECT power saving feature). The program also supports integration into broadband home gateways.
