BlueCore® BC7830™

For Handsets, PNDs and Telematics

Benefits

• Includes a multi-band GNSS radio and decimation chain optimised for use with a software GPS receiver. It is specifically architected to support multiple radio technologies.
• It is capable of operating within challenging RF environments such as within a cellular phone using a clock in the range 19.2MHz to 52MHz. Also, it can be used in PNDs or PMPs. eGPS Fine Time and Fine Frequency Aiding are also supported using the high-precision signal timestamp mechanism via a PIO.
• Includes AuriStream Bluetooth audio transfer which offers significant power reduction over the CVSD-based system when used at both ends of the link.
• The device incorporates auto-calibration and BIST routines to simplify development, type approval and production test.
• Can support receiving or transmitting FM radio broadcasts with simultaneous use of Bluetooth voice or data connections and GPS.
