Ntsuas nrug 240m (qhov tseeb thiab qhib ib puag ncig)
Siv high-precision 16M industrial siv lead ua oscillator, zaus yuam kev hauv ntiaj teb 10PPM (-40 ~ 85 °) tag nrho peb cov modules raug tshuaj xyuas thiab kuaj xyuas kom ntseeg tau tias kev ua tau zoo ntawm txhua qhov module
Chip kom zoo dua
SI24R1 yog universal low-power, high-performance 2.4GHZ xov tooj cua zaus transceiver nti, tsim los rau low-power wireless applications, kev khiav hauj lwm zaus ntawm 2400MHZ-2525MHZ, txhawb 2MBPS, 1MBPS, 250KBPS peb cov ntaub ntawv tus nqi.
SI24R1 xa hluav taws xob yog +7DBM (kho tau), qhov hluav taws xob tig tawm tsuas yog 1UA, thiab qhov tau txais rhiab heev yog -83DBM @2MHZ. Hauv kev siv daim npav ua haujlwm, lub nti yog tsaug zog ntau lub sijhawm, yog li tag nrho lub zog siv ntawm SI24R1 yog qhov tsawg heev thiab tuaj yeem ua tiav ntau dua 3 xyoos ntawm lub sijhawm ua haujlwm.
SI24R1 siv cov qauv tsim hauv tsev ntshiab thiab kev tsim khoom, uas ua kom cov kev ua tau zoo thiab cov nqi sib tw heev.
SI24R1 tau raug tsim tawm hauv xyoo 2012, nrog cov khoom zoo sib xws, kev ruaj ntseg siab, thiab tus nqi tsim nyog, thiab tau txais kev lees paub los ntawm cov neeg siv khoom hauv kev npaj.
