12 / 133 page  CC2520 DATASHEET 2.4 GHZ IEEE 802.15.4/ZIGBEE® RF TRANSCEIVER SWRS068 – DECEMBER 2007 12 WWW.TI.COM PARAMETER CONDITIONS MIN TYP MAX UNIT XOSC off, digital regulator on. State retention. 175 250 µA LPM1 current TA=-40 to 125°C, VDD=1.8 to 3.8 V, fc =2394 to 2507 MHz 1000 µA XOSC off, digital regulator off. No state retention. 30 120 nA LPM2 current TA=-40 to 125°C, VDD=1.8 to 3.8 V, fc =2394 to 2507 MHz 4.5 µA 5.5 Receive Parameters TA =25°C, VDD=3.0 V, fc =2440 MHz if nothing else stated. All parameters measured on Texas Instruments’ CC2520 EM 2.1 reference design with 50 Ω load . PARAMETER CONDITIONS MIN TYP MAX UNIT [2] requires -85 dBm -99 -98 -95 dBm Receiver sensitivity TA=-40 to 125°C, VDD=1.8 to 3.8V, fc =2394 to 2507 MHz -88 dBm Saturation [2] requires -20 dBm 6 dBm Wanted signal 3 dB above the sensitivity level, 802.15.4 modulated interferer at 802.15.4 channels: ±5 MHz from wanted signal. [2] requires 0 dB 49 dB ±10 MHz from wanted signal. [2] requires 30 dB 54 dB Interferer Rejection ±20MHz or above. Wanted signal at -82dBm. 55 dB 30 – 1000 MHz < -80 dBm Maximum Spurious Emission Conducted measurement in a 50Ω single ended load. Complies with EN 300 328, EN 300 440 class 2, FCC CFR47, Part 15 and ARIB STD-T-66 1 – 12.75 GHz -56 dBm Frequency error tolerance Input level is 3 dB above sensitivity level. +/-400 kHz IIP3 -24 dBm 5.6 Frequency Synthesizer Parameters TA =25°C, VDD=3.0 V, fc =2440 MHz if nothing else stated. All parameters measured on Texas Instruments’ CC2520 EM 2.1 reference design with 50 Ω load . PARAMETER CONDITIONS MIN TYP MAX UNIT At ±1 MHz offset from carrier -111 dBc/Hz At ±2 MHz offset from carrier -118 dBc/Hz Phase noise. Unmodulated carrier At ±5 MHz offset from carrier -128 dBc/Hz RF Frequency range Programmable in 1 MHz steps. Use 5 MHz steps for compliance with [2]. 2394 2507 MHz 5.6.1 Transmit Parameters TA =25°C, VDD=3.0 V, fc =2440 MHz if nothing else stated. All parameters measured on Texas Instruments’ CC2520 EM 2.1 reference design with 50 Ω load . PARAMETER CONDITIONS MIN TYP MAX UNIT 0 dBm setting -3 1 5 dBm +5 dBm setting 2 5 7 dBm TA=-40 to 85°C, VDD=2.0 to 3.8 V, fc =2394 to 2507 MHz -3 8 dBm TA=-40 to 85°C , VDD=1.8 to 3.8 V, fc =2394 to 2507 MHz -4 8 dBm TA=-40 to 125°C, VDD=2.0 to 3.8 V, fc =2394 to 2507 MHz -6 8 dBm Output power Note: to reduce the output power variation over temperature, it is suggested that different settings are used at different temperatures. The on-chip temperature sensor can be used for this purpose. Please see section 5.11 for more information. TA=-40 to 125°C, VDD=1.8 to 3.8 V, fc =2394 to 2507 MHz -9 8 dBm |
