half-duplex, FSK, UHF transceiver designed for low power and low-voltage wireless applications. The circuit is mainly intended for the ISM (Industrial, Scientific and Medical) frequency bands 315, 418 and 433 MHz, but can easily be programmed for operation at other frequency bands in the - 500 MHz range. The main operating parameters of CC400 can be programmed via a serial interface, thus making CC400 a very flexible and easy to use component. In a typical system CC400 will be used together with a microcontroller and a few external passive components.Features
Single chip RF transceiver Frequency range � 500 MHz High sensitivity (typical -112 dBm) Programmable output power mW (14 dBm) Small size (SSOP-28 package) Low supply voltage 3.3 V) Very few external components required FSK modulation Very low phase noise Data-rate to 9.6 kbit/s Suitable for both narrow and wide band systems Suitable for frequency hopping protocols Frequency-Lock indicator Development kit available Easy-to-use software (SmartRF Studio) for generating the CC400 configuration data

Transmit data rate 2.4 9.6 kbit/s Manchester code is required. (9.6 kbit/s equals 19.2 kBaud using Manchester code) 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 in steps of 1 kHz. Delivered to matched load. The output power is programmable in steps of 1 dB. Transmit mode, parallel equivalent. For matching details see "Input/ output matching" p.13. dBc When using high output power levels an external LC or SAW filter may be used to reduce harmonics emission to comply with ISM requirements. See p. 14.
