CC1101 433MHZ FSK无线模块 收发一体模块 数传模块
CC1101是TI公司一款高性价比的单片UHF收发器，为低功耗无线电应用而设计。它是CC1100器件的加强升级版，灵敏度更高，功耗更小，带宽更大。
CC1101拥有卓越的数据包处理能力。发送时，只需简单设置寄存器，当用户往CC1101内的TXFIFO写入数据后，器件自动在数据包内增加前导字节 (长度可控)，同步信息，CRC16校验，并根据寄存器设置将FIFO内写入的头两个字节数据标志为长度信息(此功能可选)和地址信息(可选)。接收状态下，器件自动侦测前导码，同步码，地址信息和计算并比较CRC16。此外，CC1101还支持变长数据包格式和交织功能。这些原本需要复杂算法和巨大运算量和存储空间的功能由硬件支持，MCU的编程难度大大降低，其负荷也大为减轻。

Analog Features
2-FSK, GFSK, and MSK supported as well as OOK and flexible ASK shaping
Suitable for frequency hopping systems due to a fast settling frequency synthesizer: 90μs settling time
Automatic Frequency Compensation (AFC) can be used to align the frequency synthesizer to the received center frequency
Integrated analog temperature sensor
Digital Features
Flexible support for packet oriented systems: On-chip support for sync word detection, address check, flexible packet length, and automatic CRC handling
Efficient SPI interface: All registers can be programmed with one ‘burst’ transfer
Digital RSSI output
Programmable channel filter bandwidth
Programmable Carrier Sense (CS) indicator
Programmable Preamble Quality Indicator (PQI) for improved protection against false sync word detection in random noise
Support for automatic Clear Channel Assessment (CCA) before transmitting (for listen-before-talk systems)
说明
The CC1101 is a low-cost sub- 1 GHz transceiver designed for very low-power wireless applications. The circuit is mainly intended for the ISM (Industrial, Scientific and Medical) and SRD (Short Range Device) frequency bands at 315, 433, 868, and 915 MHz, but can easily be programmed for operation at other frequencies in the 300-348 MHz, 387-464 MHz and 779-928 MHz bands.
CC1101 is an improved and code compatible version of the CC1100 RF transceiver. The main improvements on the CC1101 include:
Improved spurious response
Better close-in phase noise improving Adjacent Channel Power (ACP) performance
Higher input saturation level
Improved output power ramping
Extended frequency bands of operation, i.e.
CC1100: 400-464 MHz and 800-928 MHz
CC1101: 387-464 MHz and 779-928 MHz
The RF transceiver is integrated with a highly configurable baseband modem.
CC1101的主要应用有极低功率UHF无线收发器，315/433/868和915MHz ISM/SRD波段系统，AMR-自动仪表读数，电子消费产品，RKE-两路远程无键登录，低功率遥感勘测，住宅和建筑自动控制，无线警报和安全系统，工业监测和控制以及无线传感器网络。
