Kugadzira PCB yeAV Receiver yeHDMI Switching uye Multichannel Audio

PCB yeAV receiver inobatanidza high-bandwidth HDMI switching ine multichannel digital audio processing, DAC/ADC stages, network connectivity uye multiple amplifier channels. Izvi zvinoita kuti system ive yakasanganiswa zvisingawanzoitiki: high-speed video, low-jitter digital audio, low-noise analog signals, high-current Class-D kana Class-AB outputs uye switching power supplies zvese zvinogona kugara pamwe chete mukati me chassis imwe chete.

Highleap Electronics inogadzira uye inounganidza maPCB nemaPCBA akagadzirwa nevatengi. Zvichienderana nekwakagadzirwa, chirongwa ichi chinogona kusanganisira HDMI/digital main board, audio DSP/DAC board, amplifier board, power board kana integrated assembly, ine component sourcing, programming, inspection uye functional testing inotsanangurwa nevatengi.

1. Kugadzira uye Kugadzira PCB yeKiyi yeAV Receiver

AVR inofanira kupatsanurwa zvichienderana nerudzi rwechiratidzo uye simba. Matransceiver eHDMI nema processor anoda kudzorwa nekukurumidza; zvikamu zveDAC nepreamp zvinoda ruzha rwakaderera; maamplifiers emagetsi anoda magetsi, kupararira kwekupisa uye kudzora EMI.

• HDMI switching architecture: Tsanangura huwandu hwezvinoiswa/zvinobuda, chinangwa chaicho cheTMDS/FRL, zvinodiwa ne eARC/ARC, maitiro eEDID/HPD/HDCP uye chero maficha evhidhiyo. Chikamu chinomhanya zvakanyanya chinogona kutevera PCB yeHDMI interface misimboti yekugadzira.
• Audio DSP uye nguva yekushanda: Kugadzirisa/kuburitsa ma "multichannel decode/render", manejimendi yebass, kunonoka, EQ uye mabasa ekugadzirisa kamuri zvinoenderana ne processor yakasarudzwa uye wachi dzeaudio. Dhizaini yebhodhi inogona kuongororwa zvichienderana ne " odhiyo DSP PCB kufunga.
• Kupatsanurwa kweDAC/analog: MaDAC, maop amps uye nzira dzeanalog dzepasi-pasi dzinofanira kuparadzaniswa kubva kuma switching regulators uye ma amplifier outputs ukuwo zvichiramba zvichiratidza ma ground references.
• Kuendeswa kwesimba reamplifier: Ma amplifiers emuchina wemagetsi akawanda anodhonza magetsi akawanda. Matanho ekubuda kwespeaker-output anogona kuongororwa uchishandisa simba amplifier PCB Zvinhu zvinofanira kufungwa nezvazvo pakugadzira. Upamhi hwemhangura, ma thermal pads, zvikamu zve filter zvinobuda uye zvinobatanidza ma speaker zvinofanirwa kuenzana zvichienderana nehukuru hwemutoro unoburitswa uye huwandu hwema channel.
• Thermal management: Mapurosesa eHDMI, maDSP uye matanho emagetsi zvese zvinogona kuburitsa kupisa. Kufamba kwemhepo, ma heatsinks uye chassis coupling zvinofanirwa kusimbiswa pasi pekuiswa kwechiteshi panguva imwe chete.
• Kudzora kweEMI: Kuchinja kweHDMI neClass-D zvinomhanya zvakanyanya zvinogona kukanganisa masystem eanalog/audio kana wireless. Kuisa pasi, kuisa firita uye marongerwo azvo zvinofanirwa kutevedzera hurongwa hweEMC hwesystem.

Sei PCB yeAV receiver ichiwanzova yakaoma kupfuura PCB yesoundbar?

AVR inowanzova nema HDMI inputs akawanda, ma audio outputs akawanda akazvimiririra, analog preamp section yakakura, power-amplifier channels dzakawanda uye mhando dzakasiyana dze external interfaces. Inofanirawo kutarisira video passthrough uye audio extraction/return paths panguva imwe chete.

Ko HDMI neaudio amplifier circuitry zvinofanira kuiswa paPCB imwe chete here?

Zvinogona kuitwa, asi zvigadzirwa zvakawanda zvinobatsirwa nekupatsanurwa kwemabhodhi edhijitari/HDMI, analog/DAC uye power-amplifier. Magadzirirwo akanakisa anoenderana nehukuru hwechasi, dhizaini yeconnector, nzira yekupisa, huwandu hwemachaneli uye zvinodiwa pakugadzira/sevhisi.

2. Kuchinja kweHDMI, eARC uye Kubatanidzwa kweMultichannel Audio Signal-Chain

MaAV receiver emazuva ano anoshanda seHDMI repeater uye processor yeaudio. Sisitimu iyi inofanira kugamuchira vhidhiyo/audio kubva kunobva, kutumira kana kutumira vhidhiyo kuchiratidziro uye panguva imwe chete inotora kana kudzorera odhiyo yeDSP nekuwedzera.

• HDMI transceiver/crosspoint: Nzira dzekupinda/kubuda dzinomhanya zvakanyanya dzinofanira kushandisa nzira dzakarongwa uye dzinotanga kubudiswa neconnector zvakafanana ne HDMI PCB kugadzira.
• Nzira ye eARC/ARC: Chinogamuchira chingada kuti odhiyo idzoserwe kubva kuTV kuburikidza netambo imwe chete yeHDMI. Firmware, simba remuchina wekugadzirisa tambo uye nzira yekubatanidza zvinofanirwa kuenderana nemhinduro yeHDMI yakasarudzwa.
• Mabhazi eI²S/TDM odhiyo: Ma "multichannel digital audio link" pakati peHDMI receiver, DSP, DAC nema amplifiers anofanira kushandisa wachi dzakachena uye mapping ye "deterministic channel".
• DAC uye matanho ekutanga: Kurongeka kweruzha rushoma uye pasi zvinogona kutungamirirwa ne dhizaini yePCB yeaudio maitiro, kunyanya pakushandisa ma "analog outputs" uye ma "volume-control circuits".
• Network/wireless odhiyo: Ethernet, Wi-Fi kana Bluetooth zvinofanirwa kubatwa sema RF/noise domains akasiyana uye zvinosanganisirwa mu firmware test configuration kana zvaiswa.

HDMI 2.2 inounzawo mashandiro ane chekuita nekunonoka kwakanangana nemasisitimu e-multi-hop akadai seAV receivers nemasoundbars, asi OEM inofanira kudoma maficha chaiwo eHDMI anotsigirwa nesilicon yakasarudzwa pane kufunga kuti chinhu chitsva chega chega chiripo.

3. Multichannel Amplifier PCBA, Component Sourcing uye Kuongorora

Chikamu cheamplifier chine njodzi dzakasiyana dzekugadzira kubva kuHDMI/digital board. Mapadhi makuru ethermal, ma output inductors, electrolytics, speaker connectors uye power devices dzinofanira kugadziriswa zvichienderana nezvinodiwa pari zvino uye zvethermal.

• Kugadzirwa kweamplifier yeaudio: Highleap inogona kutsigira gungano rePCB reaudio amplifier yezvikamu zvemagetsi zvedhijitari kana zveanalog.
• Kuwanikwa kwemari kwakatenderwa: Ma HDMI transceivers, ma DSP, ma DAC, ma op amps, ma amplifier ICs uye ma PMICs anofanirwa kutevedzera zvinodzorwa nevatengi. chikamu chekutsvaga mitemo.
• AOI: AOI muPCBA inogona kuona SMT inoonekwa, connector polarity uye output-filter components dzisati dzavhara kupinda.
• X-ray: Mapakeji eBGA/LGA DSP/processor uye zvishandiso zveamplifier zvinogadziriswa pasi zvinogona kuongororwa uchishandisa X-ray kuongorora paidiwa.
• Chimiro cheHeatsink: Mapedhi ekupisa, masikuruu, maklipu uye zvinodzivirira kupisa zvinofanirwa kubatanidzwa zvichienderana nemamiriro emuchina akaburitswa kuitira kuti matanho emagetsi asanyanya kumanikidzwa kana kubatanidzwa zvisina kunaka.

Ndezvipi zvikamu zvinowanzoda kudzorwa kwakasimba kwekutsinhana muAVR?

Mienzaniso yakajairika ndeyekuti ma transceivers eHDMI, DSP/SoC, DAC, zvishandiso zvewachi, ma IC e power-amplifier, ma output inductors uye ma op amps ane ruzha rushoma nekuti mashandiro emagetsi, firmware kana maitiro ekupisa anogona kuchinja kunyangwe kana chimwe chinotsiva chichishanda pamwe chete ne footprint.

4. Kuedzwa Kwebasa reHDMI, DSP, DAC uye Amplifier Channels

Kuyedzwa kweAV receiver kunofanirwa kukamurwa muzvikamu zvekutarisa vhidhiyo, digital-audio, analog uye power-amplifier kuitira kuti kukundikana kamwe chete kusavanzike mukati mebvunzo iri nyore ye "sound present".

• Kuedzwa kwenzira yeHDMI: Simbisai nzira yega yega yekuisa/kuburitsa uye nzira yemavhidhiyo inosarudzwa nemutengi, kusanganisira eARC/ARC payakagadzirirwa.
• Kuedzwa kweDSP/firmware: Simbisa mufananidzo wakarurama, mepu yechiteshi uye nzira yekutanga yekugadzirisa odhiyo.
• Bvunzo reDAC/preamp: Yera kana simbisa nzira dzinobuda dzemhando yepamusoro zvichienderana nemiganhu yekugadzira yeOEM.
• Kuedzwa kweamplifier: Shandisa zvinhu zvakatsanangurwa kana kuti zvinhu zvinogadzirwa nemasipika kuti utarise kubuda kwechiteshi, dziviriro uye maitiro asina kujairika emagetsi/tembiricha.
• FCT yefekitori: Highleap inogona kuita kushanda kushanda nemidziyo yeaudio/video inotenderwa, zvinhu zvinotakurwa, firmware uye zvinodiwa zvekupasa/kukundikana.

5. Kuburitswa kweZvigadzirwa uye Data reRFQ reAV Receiver PCB Production

Kugadzirwa kweAVR kunoshanda zvakanyanya kana mabhodhi edhijitari, eaudio uye eamplifier aburitswa sesystem yakawiriraniswa. Ma connector pinouts, channel mapping, firmware uye chassis thermal interfaces hazvifanirwe kuchinja zvakazvimiririra pakati pema lots.

• Mapakeji ePCB: Yakaburitswa data rekugadzira mabhodhi makuru/edhijitari, eaudio uye eamplifier, kusanganisira zvinodikanwa zve controlled impedance uye copper.
• BOM: HDMI, DSP, DAC/ADC, op amp, amplifier, simba uye network zvikamu zvine zvimwe zvinotenderwa.
• Michina/kupisa: Nzvimbo dzekubatanidza chassis, heatsinks, mafeni, ma thermal pads uye ma speaker terminals.
