CEVA and ROHM Team to Develop Bluetooth 2.0+EDR Reference Design Platform

By Niladri Sekhar Nath, TMCnet Contributing Editor

CEVA (News - Alert) Inc., a leading licensor of silicon intellectual property (SIP) platform solutions and DSP cores for mobile, consumer electronics and storage applications, has teamed with ROHM (News - Alert) Co., Ltd. to offer a complete reference design platform for Bluetooth 2.0+EDR.

The combined reference design integrates ROHM's 2.0+EDR Radio with CEVA's Bluetooth 2.0+EDR baseband and protocol stack IP for a high-performance, low-power Bluetooth 2.0+EDR platform.

"CEVA's Bluetooth 2.0+EDR baseband hardware and software protocol stack IP and ROHM's 2.0+EDR Radio are already being independently integrated by mutual customers," said Paddy McWilliams, Managing Director, Communications Product Line at CEVA, in a press release. "To simplify the integration process and optimize the reference design for our collective customers, we are pleased to partner with ROHM and integrate our combined Bluetooth technologies into a reference Bluetooth 2.0+EDR platform."

CEVA-Bluetooth 2.0+EDR IP comprised of an RTL baseband engine coupled with an ANSI C software stack. It is available as a discrete IP package for use with 3rd party embedded processors or it may be licensed together with a CEVA DSP for a complete Bluetooth platform. Such a platform can be also integrated with a complete set of audio codecs, voice codecs, echo cancellation and noise suppression algorithms, yielding an integrated Bluetooth and multimedia solution.

"The silicon performance of our Bluetooth 2.0+EDR Radio along with the CEVA-Bluetooth IP at the recent UnPlugFest revealed a very competitive combined Bluetooth solution," said Hiroshi Ohyabu, Group Manager, Digital Network Project at ROHM. "We are delighted to further co-operate with CEVA in creating this platform and address the strong demand for a complete Bluetooth 2.0+EDR reference design from our customers."

ROHM Bluetooth 2.0+EDR Radio consists of LNA, PA, TX/RX switch, Crystal Oscillator, regulator, VCO and Digital modulator/demodulator for FSK/PSK. It is a full CMOS IC RF transceiver, offering high performance and low power consumption for 2.4GHz band Bluetooth applications.
