By uniting interference technology with clean signal delivery, Cypress Semiconductor Corp. (News - Alert) has successfully introduced a demonstration kit for a VoIP headset. The new CY4638 VoIP Demonstration Kit pairs the interference immunity of Cypress's low-power WirelessUSB LP (CYRF6936) 2.4-GHz radio system-on-chip with the clean signal delivery of Winbond Electronics Corporation's W681360 CODEC to provide an easily replicated, fast time-to-market design. According to Cypress Semiconductor, the new solution results in fewer interruptions than headsets using competing wireless technologies, and offers a range over 20-meters.

 

The WirelessUSB LP headset board includes a Cypress Wireless enCoRe II flash microcontroller, a low power Winbond CODEC, and a rechargeable battery with the radio module. Winbond's W681360 single-channel voice CODEC is a 13-bit linear analog-to-digital and digital-to-analog converter. The W681360 offers high performance voice quality at the lowest power consumption in the industry, directly impacting talk-time and battery life.

 

"A primary concern of VoIP headset manufacturers is dropping packets due to interference, making the extremely robust WirelessUSB LP solution a natural fit to deliver an uninterrupted flow of data," said Matt Branda, senior strategic marketing manager for Wireless Products at Cypress. "Not only does the interference immunity of our WirelessUSB protocol outperform other 2.4-GHz solutions, its robust operation outdoes more expensive Bluetooth and DECT (News - Alert) solutions as well. When you add in the excellent signal quality of the Winbond Codec, the CY4638 VoIP Demonstration Kit provides the groundwork for a winning VoIP headset."

 

The CY4638 VoIP Headset Development Kit includes items such as an innovative dual antenna design for robustness; a small form-factor bridge; and hardware schematics, bill of materials and firmware for Wireless VoIP headset design.
