Nordic e sa tsoa qala sehlahisoa se secha sa Bluetooth audio portfolio, Nordic nRF5340 Audio Development Kit. Audio DK ena e kenyelletsa ntho e 'ngoe le e 'ngoe e hlokahalang ho thusa batho ba ntlafatsang ho nka monyetla ka boleng ba molumo o phahameng, tšebeliso e tlaase ea matla le lisebelisoa tsa stereo tse se nang mohala tsa Bluetooth LE Audio.
Nordic e phatlalatsa nRF5340 Audio Development Kit, sethala sa moralo bakeng sa nts'etsopele e potlakileng ea lihlahisoa tsa Bluetooth® LE Audio. NRF5340 ke SoC ea pele e se nang mohala lefatšeng e nang le li-processor tse peli tsa Arm® Cortex®-M33, tse loketseng LE Audio le lits'ebetso tse ling tse rarahaneng tsa Internet of Things (IoT).
Sehlopha sa Bluetooth Special Interest Group (SIG) se hlalosa LE Audio e le "bokamoso ba molumo o se nang mohala". Theknoloji ena e ipapisitse le khoutu ea khokahanyo e sa rarahanang ea LC3, e leng ntlafatso ho codec ea "subband" e tlase e rarahaneng (SBC) e sebelisoang ke Classic Audio.
LC3 e netefatsa hore LE Audio e na le boleng bo holimo ba molumo le bophelo bo bolelele ba betri ho feta Classic Audio maemong ohle a ts'ebeliso. Teko e pharalletseng ea ho mamela e bonts'itse hore LC3 e fana ka boleng ba molumo o betere ho feta SBC ka sekhahla se ts'oanang sa sampole maemong ohle a sampole, 'me e fana ka boleng bo lekanang kapa bo betere ba molumo ka halofo ea sekhahla sa data se se nang mohala.
Litefiso tse tlase tsa data ke ntlha ea bohlokoa ho fokotsa tšebeliso ea matla lihlahisoa tsa LE Audio. LE Audio e boetse e tlisa True Wireless Stereo (TWS) le likarolo tse ling tse ncha lits'ebetsong tsa audio tse se nang mohala, ho kenyeletsoa Audio Sharing.
Audio DK's core nRF5340 SoC e kopanya processor ea ts'ebeliso e sebetsang hantle haholo e nang le processor ea netweke ea Ultra-low-power network bakeng sa ts'ebetso e ntle ea matla le ts'ebetso e phahameng mohahong oa li-dual-core. 128 MHz Arm Cortex-M33 application processor e na le 1 MB ea flash le 512 KB ea RAM, e etsang hore e be e loketseng ho sebetsana le lits'ebetso tsa tloaelo le li-codec tsa molumo joalo ka LC3.
Sesebelisoa sa marang-rang sa 64 MHz Arm Cortex-M33 se na le 256 KB ea memori ea flash le 64 KB ea RAM, 'me se matlafalitsoe ho tsamaisa software ea protocol ea Nordic Bluetooth LE Audio RF. NRF Connect SDK ke sethala sa nts'etsopele sa nRF5340 SoC se fanang ka ts'ehetso ea boemo ba boto ea nRF5340 Audio DK le ho tšehetsa LE Audio, Bluetooth Low Energy, Thread le lisebelisoa tse ling.
Ntle le nRF5340 SoC, Audio DK e na le taolo ea matla ea Nordic's nPM1100 IC (PMIC) le Cirrus Logic's CS47L63 audio digital signal processor (DSP).
NPM1100 e na le taolo e sebetsang hantle haholo ea buck le tjhaja e kopantsoeng ea betri e fihlang ho 400mA ea ho tjhaja hajoale ka mokhoa o monyane haholo, e etsang hore e be PMIC e loketseng bakeng sa lits'ebetso tse haelloang ke sebaka joalo ka li-earbud tsa TWS. CS47L63 e na le DAC e sebetsang hantle haholo le mokhanni oa phapano o ntlafalitsoeng bakeng sa khokahanyo e tobileng ho meroalo ea li-headphone tsa kantle bakeng sa lihlahisoa tsa li-earbud tse nang le mono le libui tse otlolohileng feela.
