CEVA, ROHM co-develop Bluetooth 2.0+EDR ref design

CEVAInc. and ROHMCo. Ltd have partnered to offer a complete reference designplatform for Bluetooth2.0+EDR.

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

CEVA-Bluetooth 2.0+EDR IP consists 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. The platform can be also coupled with a complete set of audio codecs, voice codecs, echo cancellation and noise suppression algorithms, yielding an integrated Bluetooth and multimedia solution.

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. The chip is integrated to minimize the use of external components and is available in VQFN40 package.

"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. McWilliams added that the collaboration aims to simplify the integration process and optimize the reference design.

"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.
