Nordic ewepụtala ngwaahịa Pọtụfoliyo ọdịyo Bluetooth ọhụrụ, Nordic nRF5340 Audio Development Kit. DK ọdịyo a gụnyere ihe niile achọrọ iji nyere ndị mmepe aka iji uru dị elu dị elu, ike dị ala na nkwalite stereo ikuku nke Bluetooth LE Audio.
Nordic na-akpọsa ngwa nRF5340 Audio Development Kit, usoro nhazi maka mmepe ngwa ngwa nke ngwaahịa Bluetooth® LE Audio. NRF5340 bụ SoC ikuku izizi n'ụwa nwere ihe nrụpụta Arm® Cortex®-M33, dị mma maka LE Audio na ngwa ịntanetị siri ike (IoT).
Otu mmasị pụrụ iche Bluetooth (SIG) na-akọwa LE Audio dị ka "ọdịnihu nke ụda ikuku". Teknụzụ a dabere na codec nzikọrịta ozi dị ala LC3, nkwalite na codec subband dị ala (SBC) nke Classic Audio na-eji.
LC3 na-akwado na LE Audio nwere ogo ọdịyo dị elu yana ogologo ndụ batrị karịa Classic Audio n'ihe niile eji eme ihe. Nnwale ige ntị sara mbara egosila na LC3 na-enye ogo ọdịyo ka mma karịa SBC n'otu ọnụego nlele na ọnụego nlele niile, ma na-ebuga nha nha ma ọ bụ ka mma ọdịyo na ọkara ọnụego data ikuku.
Ọnụego data dị ala bụ isi ihe na-ebelata oriri ike na ngwaahịa LE Audio. LE Audio na-ewetakwa True Wireless Stereo (TWS) na atụmatụ ọhụrụ ndị ọzọ na ngwa ọdịyo ikuku, gụnyere Ịkekọrịta Audio.
The Audio DK's core nRF5340 SoC na-ejikọta ngwa nrụpụta ngwa dị elu yana ihe nrụpụta netwọkụ ultra-obere ike zuru oke maka ịrụ ọrụ ike kacha mma yana ịrụ ọrụ dị elu n'ime ihe owuwu abụọ. Ngwa ngwa 128 MHz Arm Cortex-M33 nwere 1 MB nke flash na 512 KB nke RAM, na-eme ka ọ dị mma maka ijikwa ngwa ọdịnala na codecs ọdịyo dị ka LC3.
Ihe nhazi netwọkụ 64 MHz Arm Cortex-M33 nwere 256 KB nke ebe nchekwa flash yana 64 KB nke RAM, ma bụrụkwa nke kachasị ike iji mee Nordic Bluetooth LE Audio RF protocol software. NRF Jikọọ SDK bụ nRF5340 SoC mmepe n'elu ikpo okwu nke na-enye nRF5340 Audio DK nkwado ọkwa ọkwa ma na-akwado LE Audio, Bluetooth Low Energy, Thread na ngwa ndị ọzọ.
Na mgbakwunye na nRF5340 SoC, Audio DK na-egosipụta Nordic's nPM1100 ike njikwa IC (PMIC) na Cirrus Logic's CS47L63 audio digital signal processor (DSP).
NPM1100 na-egosipụta onye na-ahụ maka njikwa ego na-arụ ọrụ nke ọma yana chaja batrị agbakwunyere nke nwere ihe ruru 400mA na-akwụ ụgwọ ugbu a n'ụdị dị obere, na-eme ka ọ bụrụ PMIC dị mma maka ngwa nwere oghere dị ka ntị ntị TWS. CS47L63 nwere DAC na-arụ ọrụ dị elu yana onye ọkwọ ụgbọ ala dị iche iche ahaziri maka njikọ kpọmkwem na ibu ekweisi mpụga maka ngwaahịa ntị nwere mono na mmepụta okwu naanị.
