Narrowband RF transceiver chip meets stringent ARIB standard

16 July 2003 Telecoms, Datacoms, Wireless, IoT

Chipcon has upgraded its 402 to 470 MHz and 804 to 940 MHz RF transceiver, the CC1020, to meet the stringent requirements of the ARIB STD-T67 standard for narrowband, multichannel applications.

Launched in November 2002, the CC1020 is now the only RF transceiver that complies with 12,5 kHz channel spacing operation under the ARIB STD-T67 and with 25 kHz channel spacing operation under the European standard EN 300 220. The ARIB standard specifies the requirements to license free short range radio devices for use in Japan. Similar requirements are adopted by Korea. Contrary to European and US regulations, the ARIB standard allows only narrowband operation using 12,5 kHz and 25 kHz channel spacing. This means strict requirements to frequency stability, adjacent channel power and occupied bandwidth for the transmitter part, and adjacent channel selectivity and image rejection for the receiver.

Key features of the CC1020 (32-pin QFN package) include: receiver sensitivity up to -121 dBm, programmable data rates up to 153,6 Kbps, high selectivity (for 25 kHz systems: 34 dB adjacent channel rejection and 40 dB alternate channel rejection; for 12 kHz systems: 30 dB adjacent channel rejection and 40 dB alternate channel rejection), 2,3 to 3,6 V power supply, narrowband digital RSSI function, Intelligent wake-up circuitry for power management and fully on-chip VCO.
