CIE Components in Electronics
Dialog Semiconductor, a supplier of highly integrated power management, audio and short range wireless technologies, has announced that Jabra has adopted the company”s short-range wireless audio ICs to create the Jabra PRO 9450 Flex JP headset, which connects with office phones and PCs running VoIP calling software, such as Skype or Microsoft Lync.
The PRO 9450 Flex JP is a high-performance, lightweight wireless headset and is the first system to use Dialog”s chips for the Japanese variant of the DECT standard. It has up to a 120-metre range, is able to deliver up to 10 hours of talk time and integrates Dialog”s SC14480 single-chip CAT-iq IC in the headset, with Dialog”s LMX4180 DECT transceiver and SC14450 high-end baseband processor in the base-station.
The headset has been optimised for noisy work environments, while providing wireless audio quality. The headset runs Dialog”s Perfect Acoustic Echo Canceller (PAEC) and background noise cancellation with a wideband audio codec.
For wireless audio applications, the DECT standard enables energy efficiency enhancements, easy pairing, wide-band audio data rates and secure connectivity. Dialog is the market leader in this segment and its portfolio covers all regional versions of DECT plus the 2.4 GHz DCT protocol and also includes the DECT ULE family of products; SmartPulse. The adoption by Jabra further extends the recent deployment of Dialog”s DECT technologies into a broader range of short range wireless audio applications; including professional headsets, wireless microphones and gaming.
“A growing number of OEMs are realising the potential that DECT has in enabling long range, high-performance, low power robust systems with ample bandwidth; integrating the technology into a greater range of applications,” said Asmund Tielens, Vice President & General Manager Connectivity and Automotive & Industrial Business Group of Dialog. “Jabra was among the first to see this potential and is a brand renowned for innovation, exceptional quality and sleek design; and the 9450 Flex JP is no exception,” concluded Tielens.
The SC14480 is a monolithically integrated DECT/DCT solution in standard CMOS and integrates Flash memory and a high-performance Gen2DSP core, which provides the processing power to support the enhanced voice quality of the CAT-iq standard and other features. The SC14480 can operate directly from Li-ion cells, reducing external component costs and makes the chip ideal for headset applications.
The device”s processor uses a multi-core architecture and delivers 240 MIPS of processing power. It features a 16-bit CompactRISC(TM) processor, plus two user-programmable Gen2DSPs and runs multiple audio codecs with best-in-class acoustic echo cancellation alongside other embedded applications. In addition, the SC14450 supports a variety of external memories, and features an integrated class D amplifier, power and battery management options, a white LED driver and a wide variety of peripheral interfaces including master / slave PCM, UART, SPI, dual-access bus and USB client.
