AX5042 ISM long-range RF transceiver |
Long range, narrow-band, RF transceiver IC
The AX5042 is a single-chip ultra narrowband RF transceiver for the 433/868/915
MHz SRD and ISM bands. The AX5042 offers very long range with a small number components.
The AX5042 transceiver consists of an integrated RF front-end with
modulator and demodulator and flexible communication controller. Base
band data processing is implemented in the integrated communication
controller for user-friendly communication and configuration via SPI
interface. The integrated HDLC protocol guarantees exceptionaly compact code and small CPU overhead. The AFC enables the user to use low end crystals.
The AX5042's flexibility make it ideal for SRD applications such as sensor
networks, access control systems or home automation applications using
the Konnex, ARIB or other standards.
For narrow-band operation we recommend the usage of a TCXO. North american as well as european standards require freqency tolerances of 0.5 ppm to 1.5 ppm for many narrow-band applications.
Features
- Single chip ASK/FSK/PSK/MSK/GFSK/GMSK/OQPSK UHF transceiver
- Configurable for use in 400 - 470 MHz and 800 - 940 MHz SRD bands
- Ultra-narrow-band receiver with programmable channel filter in the range 4.8 - 600 kHz
- -122 dBm sensitivity with 1.2 kBit/s at BER 10-3 without FEC
- Up to +13 dBm programmable transmitter power amplifier
- Capable of data rates 1 - 600 kbps.
- Spectral shaping for ASK, FSK and PSK
- 802.15.4 compatible
- RS-232 (UART) compatible
- 1 Hz frequency step
- Few external components, low cost crystals
- Automatic frequency control
- SPI micro controller interface
- Forward error correction integrated (FEC)
- HDLC protocol
- Low power: 17 - 23 mA at 2.5 V supply during receive and 13 - 37 mA during transmit
- Operating temperature range –40 to 85 C
- Small package size: 5x5mm, QFN28 package
All transmit currents are measured on a PCB optimized for maximum output power. With optimized matching networks for lower power significant lower currents can be achieved, e.g. 15 mA for 0 dBm.
