描述 Description

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.The RF transceiver is integrated with a highly configurable baseband modem. The modem supports various modulation formats and has a configurable data rate up to 600 kbps.CC1101 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 and the 64- byte transmit/receive FIFOs of CC1101 can be controlled via an SPI interface. In a typical system, the CC1101 will be used together with a microcontroller and a few additional passive components.The CC1190 850-950 MHz range extender [21] can be used with CC1101 in long range applications for improved sensitivity and higher output power.

特性 Features

• RF Performance
• –116 dBm at 0.6 kBaud, 433 MHz, 1% packet error rate
• Low current consumption (14.7 mA in RX, 1.2 kBaud, 868 MHz)
• Excellent receiver selectivity and blocking performance
• Frequency bands: 300-348 MHz, 387-464 MHz and 779-928 MHz
• Analog Features
• Suitable for frequency hopping systems due to a fast settling frequency synthesizer; 75 µs settling time
• Integrated analog temperature sensor
• Digital Features
• Efficient SPI interface; All registers can be programmed with one \"burst\" transfer
• Programmable channel filter bandwidth
• Programmable Preamble Quality Indicator (PQI) for improved protection against false sync word detection in random noise
• Support for per-package Link Quality Indication (LQI)
• Low-Power Features
• Fast startup time; 240 µs from sleep to RX or TX mode (measured on EM reference design [1] and [2])
• Separate 64-byte RX and TX data FIFOs (enables burst mode data transmission)
• General
• Green package: RoHS compliant and no antimony or bromine
• Suited for systems targeting compliance with EN 300 220 (Europe) and FCC CFR Part 15 (US)
• Support for asynchronous and synchronous serial receive/transmit mode for backwards compatibility with existing radio communication protocols
• Improved Range using CC1190
• High sensitivity–118 dBm at 1.2 kBaud, 868 MHz, 1% packet error rate–120 dBm at 1.2 kBaud, 915 MHz, 1% packet error rate
• +27 dBm output power at 915 MHz
• Reduced Battery Current using TPS62730
• In RX, the current drawn from a 3.6 V battery is typically less than 11 mA when TPS62730 output voltage is 2.1 V. When connecting CC1101 directly to a 3.6 V battery the current drawn is typically 17 mA
• When CC1101 enters SLEEP mode, the TPS62730 can be put in bypass mode for very low power down current
• The CC1101 is connected to the battery via an integrated 2.1 Ω (typical) switch in bypass mode
