Single Chip Ultra Low Power RF Transceiver For The 315/433/868/915 MHZ SRD Band


Features, Applications

Very low power UHF wireless data transmitters and receivers and 915 MHz ISM/SRD band systems RKE � Two-way Remote Keyless Entry Home automation Wireless alarm and security systems AMR � Automatic Meter Reading Low power telemetry Toys

is a true single-chip UHF transceiver designed for very low power and very low voltage wireless applications. The circuit is mainly intended for the ISM (Industrial, Scientific and Medical) and SRD (Short Range Device) frequency bands 433, 868 and 915 MHz, but can easily be programmed for operation at other frequencies in the 300-1000 MHz range. The main operating parameters of CC1000 can be programmed via an easy-tointerface serial bus, thus making CC1000 a very flexible and easy to use transceiver. In a typical system CC1000 will be used together with a microcontroller and a few external passive components.

Transmit data rate 0.6 76.8 kBaud NRZ or Manchester encoding. 76.8 kBaud equals 76.8 kbit/s using NRZ coding. See page 14. The frequency corresponding to the digital "0" is denoted f0, while f1 corresponds to a digital "1". The frequency separation is f1-f0. The RF carrier frequency, fc, is then given by fc=(f0+f1)/2. (The frequency deviation is given fd=+/-(f1-f0)/2 ) The frequency separation is programmable 250 Hz steps. 65 kHz is the minimum guaranteed separation at 1 MHz reference frequency. Larger separations can be achieved at higher reference frequencies. Delivered to 50 load. The output power is programmable. Transmit mode. For matching details see "Input/ output matching" p.28. An external LC or SAW filter should be used to reduce harmonics emission to comply with SRD requirements. See p.34.
