I-Nordic isandula ukuphehlelela imveliso entsha yepotfoliyo yomsindo weBluetooth, iNordic nRF5340 Audio Development Kit. Le DK yomsindo ibandakanya yonke into efunekayo ukunceda abaphuhlisi basebenzise umgangatho wesandi esiphakamileyo, ukusetyenziswa kwamandla aphantsi kunye nezincedisi zestereo ezingenazingcingo zeBluetooth LE Audio.
I-Nordic ibhengeza i-nRF5340 Audio Development Kit, iqonga loyilo lophuhliso olukhawulezayo lweemveliso zeBluetooth® LE Audio. I-nRF5340 yi-SoC yokuqala yehlabathi engenazingcingo ene-Arm® Cortex®-M33 processors ezimbini, ilungele i-LE Audio kunye nezinye iinkqubo ezintsonkothileyo ze-Intanethi yeZinto (IoT).
Iqela leBluetooth Special Interest Group (SIG) lichaza i-LE Audio njenge "ikamva lesandi esingenazingcingo". Le teknoloji isekelwe kwi-codec ye-LC3 yonxibelelwano oluntsonkothileyo, uphuculo kwi-codec ye-subband ye-low-complexity (SBC) esetyenziswa yi-Classic Audio.
I-LC3 iqinisekisa ukuba i-LE Audio inomgangatho ophezulu womsindo kunye nobomi bebhetri obude kune-Classic Audio kuzo zonke iimeko zokusetyenziswa. Uvavanyo olubanzi lokumamela lubonise ukuba i-LC3 ibonelela ngomgangatho womsindo ongcono kune-SBC kwireyithi yesampulu efanayo kuzo zonke iireyithi zesampulu, kwaye ihambisa umgangatho olinganayo okanye ongcono womsindo kwisiqingatha sedatha engenazingcingo.
Amaxabiso asezantsi edatha yinto ephambili ekunciphiseni ukusetyenziswa kwamandla kwiimveliso ze-LE Audio. I-LE Audio izisa i-Tee Wireless Stereo (TWS) kunye nezinye izinto ezintsha kwizicelo zeaudio ezingenazingcingo, kubandakanya Ukwabelana ngomsindo.
I-Audio DK's core nRF5340 SoC idibanisa iprosesa yesicelo esebenza kakhulu kunye neprosesa yenethiwekhi yamandla asezantsi ecwangciseke ngokupheleleyo ukuze asebenze ngamandla kunye nokusebenza okuphezulu kuyilo lwe-double-core core. I-128 MHz Arm Cortex-M33 ye-application processor iqulethe i-1 MB yeflash kunye ne-512 KB ye-RAM, iyenza ilungele ukuphatha izicelo zesiko kunye neekhowudi zomsindo ezifana ne-LC3.
I-64 MHz Arm Cortex-M33 iprosesa yenethiwekhi ine-256 KB yememori ye-flash kunye ne-64 KB ye-RAM, kwaye inikwe amandla okwenza iprotocol ye-Nordic Bluetooth LE Audio RF. I-nRF Connect SDK yi-nRF5340 SoC iqonga lophuhliso olubonelela ngenkxaso yenqanaba lebhodi ye-nRF5340 ye-Audio DK kunye nenkxaso ye-LE Audio, iBluetooth Low Energy, Thread kunye nezinye izicelo.
Ukongeza kwi-nRF5340 SoC, i-Audio DK ifaka i-Nordic's nPM1100 yolawulo lwamandla e-IC (PMIC) kunye ne-Cirrus Logic's CS47L63 iprosesa yomsindo wedijithali yedijithali (DSP).
I-nPM1100 ibonakalisa isilawuli sebhaki esilungelelanisiweyo kunye netshaja edibeneyo yebhetri ukuya kuthi ga kwi-400mA yangoku yokutshaja kwifom encinci kakhulu, iyenza ibe yi-PMIC efanelekileyo kwizicelo ezixinzelelekileyo njengee-earbuds ze-TWS. I-CS47L63 ine-DAC esebenza kakhulu kunye nomqhubi ophumayo owahlukileyo olungiselelwe uqhagamshelo oluthe ngqo kwimithwalo yangaphandle ye-headphone yeemveliso ze-earbud ezineemono kunye neziphumo zesithethi esithe ngqo kuphela.
