Umfanekiso 4-1. ISicelo seSiseko esiSiseko (ipakethe yeepin ezingama-48)

I-capacitors ye-bypass power supply (CB2, CB4) ixhunywe kwi-pin yangaphandle yokubonelela nge-analog (EVDD, i-pin 44) kunye nepini yokubonelela ngedijithali yangaphandle (DEVDD, pin 16). I-capacitor C1 inikezela ukudibanisa kwe-AC efunekayo ye-RFN / RFP.
Izikhonkwane ezidadayo zinokubangela ukuchithwa kwamandla okugqithisileyo (umz. ngexesha lombane). Kufuneka ziqhagamshelwe kumthombo ofanelekileyo. I-GPIO ayinakuqhagamshelwa kumhlaba okanye kubonelelo lwamandla ngokuthe ngqo.
Izikhonkwane zokufakwa kwedijithali i-TST kunye ne-CLKI kufuneka ziqhagamshelwe. Ukuba i-pin TST ayinakuze isetyenziswe inokuqhagamshelwa kwi-AVSS ngelixa i-CLKI engasetyenziswanga inokuqhagamshelwa kwi-DVSS (jonga isahluko "Izikhonkwane ezingasetyenziswanga").
I-Capacitors CB1 kunye ne-CB3 zi-bypass capacitors ze-analog edibeneyo kunye ne-digital voltagabalawuli ukuqinisekisa ukusebenza okuzinzile kunye nokuphucula ukhuseleko lwengxolo.
I-Capacitors kufuneka ibekwe ngokusondeleyo kunokwenzeka kwizikhonkwane kwaye kufuneka ibe nokuchasana okuphantsi kunye nokudibanisa okuphantsi kwe-inductance kumhlaba ukufezekisa ukusebenza kakuhle.

I-crystal (XTAL), i-capacitors yomthwalo emibini (i-CX1, i-CX2), kunye neesekethe zangaphakathi ezixhunywe kwiikhonkwane ze-XTAL1 kunye ne-XTAL2 zenza i-crystal oscillator ye-16MHz ye-transceiver ye-2.4GHz. Ukufezekisa ukuchaneka okugqwesileyo kunye nokuzinza kwereferensi rhoqo, i-capacitances enkulu ye-parasitic kufuneka igwenywe. Imigca yeCrystal kufuneka ihanjiswe ngokufutshane kangangoko kwaye ingabi kufutshane neempawu zedijithali ze-I/O. Oku kufuneka ngokukodwa kwiiNdlela zeNkalo eziPhezulu zeDatha.
I-crystal ye-32.768 kHz ixhunywe kumandla aphantsi angaphakathi (i-sub 1µA) i-crystal oscillator inikeza ireferensi yexesha elizinzile kuzo zonke iindlela zamandla aphantsi kuquka i-32 Bit IEEE 802.15.4 I-Symbol Counter ("I-MAC Symbol Counter") kunye nesicelo sexesha langempela usebenzisa i-asynchronous. i-timer T / C2 ("I-Timer / Counter2 ene-PWM kunye ne-Asynchronous Operation").
Iyonke i-shunt capacitance equka i-CX3, i-CX4 akufuneki idlule kwi-15pF kuzo zombini izikhonkwane.
Unikezelo oluphantsi kakhulu lwangoku lwe-oscillator lufuna ukucwangciswa ngokucophelela kwe-PCB kwaye nayiphi na indlela yokuvuza kufuneka igwenywe.
I-Crosstalk kunye ne-radiation ukusuka ekutshintsheni imiqondiso yedijithali ukuya kwizikhonkwane zekristale okanye izikhonkwane zeRF zinokuthoba umgangatho wokusebenza kwenkqubo. Ukucwangciswa kwezicwangciso ezincinci zamandla okuqhuba isignali yemveliso yedijithali iyacetyiswa (jonga "i-DPDS0 - iRejista yaMandla oMqhubi wePort 0").
