描述The CC1120 device is a fully integrated single-chip radio transceiver designed for high performance at very low-power and low-voltage operation in cost-effective wireless systems. All filters are integrated, thus removing the need for costly external SAW and IF filters. The device is mainly intended for Industrial, Scientific, and Medical (ISM) applications and Short Range Device (SRD) frequency bands at 164 to 192 MHz, 274 to 320 MHz, 410 to 480 MHz, and 820 to 960 MHz. The CC1120 device provides extensive hardware support for packet handling, data buffering, burst transmissions, clear channel assessment, link quality indication, and wake-on-radio. The main operating parameters of the CC1120 device can be controlled through an SPI interface. In a typical system, the CC1120 device is used with a microcontroller and only a few external passive components.特性 High-Performance, Single-Chip Transceiver Adjacent Channel Selectivity: 64 dB at 12.5-kHz OffsetBlocking Performance: 91 dB at 10 MHz Excellent Receiver Sensitivity: –123 dBm at 1.2 kbps –110 dBm at 50 kbps –127 dBm Using Built-in Coding GainVery Low Phase Noise: –111 dBc/Hz at 10-kHz Offset Suitable for Systems Targeting ETSI Category 1 Compliance in 169-MHz and 433-MHz Bands High Spectral Efficiency (9.6 kbps in 12.5-kHz Channel in Compliance With FCC Narrowbanding Mandate) Separate 128-Byte RX and TX FIFOs Support for Seamless Integration With the CC1190 Device for Increased Range Giving up to 3-dB Improvement in Sensitivity and up to +27-dBm Output Power Power Supply Wide Supply Voltage Range (2.0 V to 3.6 V) Low Current Consumption: RX: 2 mA in RX Sniff Mode RX: 17 mA Peak Current in Low-Power Mode RX: 22 mA Peak Current in High-Performance Mode TX: 45 mA at +14 dBm Power Down: 0.12 µA (0.5 µA With eWOR Timer Running) Programmable Output Power up to +16 dBm With 0.4-dB Step Size Automatic Output Power Ramping Configurable Data Rates: 0 to 200 kbps Supported Modulation Formats: 2-FSK, 2-GFSK, 4-FSK, 4-GFSK, MSK, OOKWaveMatch: Advanced Digital Signal Processing for Improved Sync Detect Performance RoHS-Compliant 5-mm × 5-mm No-Lead QFN 32-Pin Package (RHB) Regulations – Suitable for Systems Targeting Compliance With Europe: ETSI EN 300 220, ETSI EN 54-25 US: FCC CFR47 Part 15, FCC CFR47 Part 90, 24, and 101 Japan: ARIB RCR STD-T30, ARIB STD-T67, ARIB STD-T108 Peripherals and Support Functions Enhanced Wake-On-Radio (eWOR) Functionality for Automatic Low-Power Receive Polling Includes Functions for Antenna Diversity Support Support for Retransmissions Support for Automatic Acknowledge of Received Packets TCXO Support and Control, Also in Power Modes Automatic Clear Channel Assessment (CCA) for Listen-Before-Talk (LBT) Systems Built-in Coding Gain Support for Increased Range and Robustness Digital RSSI Measurement Temperature Sensor
