AX5031中文资料RF Transmitter IC, Low Power, Highly Efficient数据手册ONSEMI规格书

描述 Description

The AX5031 is a universal single chip, low power RF-transmitter for the 433/868/915 MHz bands. AX5031 offers output power of up to 15 dBm at data rates of up to 350 kbps for FSK modulated data and up to 2000 kbps for ASK or PSK modulated data. It is a highly integrated, flexible, low power and low cost solution that supports multi channel operation for channels bandwidths above 40 kHz. Designed for low power and direct battery operation.
An integrated voltage regulation system allows the direct use of batteries and short start-up times enable time- and energy-efficient protocols. The high efficiency PA has a flat output power characteristic over supply voltage and temperature. These performance details make the AX5031 ideal for battery powered portable applications.
The AX5031 supports FSK, GFSK, MSK, 4-FSK, PSK and ASK modulations. All modulations are shaped. The AX5031 features an easy to use protocol implemented in hardware. This guarantees shortest code size and lowest CPU usage of a microcontroller. CRCs are calculated automatically. Digital spread spectrum is possible on all modulations.
External components are only a crystal, an antenna and a few passive components. All parameters of the AX5031 including modulation, frequency, deviation and output power can be programmed via an SPI interface. Systems built with the AX5031 provide cost-efficient, longest range communication links.
