Rev 1.0 10/14Copyright © 2014 by Silicon LaboratoriesSi4468/7Si4468/7H IGH-P ERFORMANCE, L OW-C URRENT TRANSCEIVERFeaturesApplicationsDescriptionSilicon Laboratories' Si446x devices are high-performance, low-currenttransceivers covering the sub-GHz frequency bands from 142 to 1050 MHz. Theradios are part of the EZRadioPRO® family, which includes a complete line oftransmitters, receivers, and transceivers covering a wide range of applications. Ahigh level of integration including support for IEEE 802.15.4 features enablesstandards based sub GHz networking solutions. All parts offer outstandingsensitivity of –133 dBm while achieving extremely low active and standby currentconsumption. The Si4468/7 offers frequency coverage in all major bands. TheSi446x includes optimal phase noise, blocking, and selectivity performance fornarrow band and licensed band applications, such as FCC Part90 and 169 MHzwireless MBus. The 69 dB adjacent channel selectivity with 12.5 kHz channelspacing ensures robust receive operation in harsh RF conditions, which isparticularly important for narrow band operation. The Si4468 offers exceptionaloutput power of up to 20 dBm with outstanding TX efficiency. The high outputpower and sensitivity results in an industry-leading link budget of 155 dB allowingextended ranges and highly robust communication links. The Si4467 active modeTX current consumption of 18 mA at 10 dBm and RX current of 10 mA coupledwith extremely low standby current and fast wake times ensure extended batterylife in the most demanding applications. The Si4468 can achieve up to 27 dBmoutput power with built-in ramping control of a low-cost external FET. The devicescan meet worldwide regulatory standards: FCC, ETSI, and ARIB. All devices aredesigned to be compliant with 802.15.4g and WMBus smart metering standards.The devices are highly flexible and can be configured via the WirelessDevelopment Suite (WDS) available at www.silabs.com.Frequency range = 142–1050 MHzReceive sensitivity = –133 dBm @100 bps plus fast-scanning AFC forstandard TCXO applicationsModulation(G)FSK, 4(G)FSK, (G)MSKOOKMax output power 20 dBm (Si4468) 13 dBm (Si4467)PA support for 27 or 30 dBmLow active power consumption10/13 mA RX18 mA TX at 10 dBm (Si4467)Ultra low current powerdown modes30 nA shutdown, 40 nA standbyPreamble sense mode6 mA average RX current at1.2 kbps10 µA average RX current at50 kbps and 1 sec sleep intervalFast preamble detection1 byte preamble detectionData rate = 100 bps to 1 MbpsFast wake and hop timesPower supply = 1.8 to 3.8 VExcellent selectivity performance69 dB adjacent channel79 dB blocking at 1 MHzAntenna diversity and T/R switch controlHighly configurable packet handlerTX and RX 64 byte FIFOs129 bytes dedicated Tx or Rx FIFOAuto frequency control (AFC)Automatic gain control (AGC)Low BOMLow battery detectorTemperature sensor20-Pin QFN packageSub-GHz 802.15.4 mesh network readyIEEE 802.15.4g, and WMBus compliantSuitable for FCC Part 90 Mask D, FCCpart 15.247, 15,231, 15,249, ARIB T-108,T-96, T-67, RCR STD-30, ChinaregulatoryETSI Category I OperationEN 300 220Smart metering (802.15.4g and WMBus)802.15.4 mesh networkingHome security and alarmTelemetryGarage and gate openersStar and point-to-point networksHome automationUltra narrowband, long rangeapplicationsIndustrial controlSensor networksHealth monitorsElectronic shelf labelsLow power wireless sensornodesPatents pendingPin AssignmentsGNDPAD1231718192011121314678945161015 nSELSDISDOSCLKNCSDNTXnIRQRXpRXn
