Kugadzira PCB yeHome Theatre processor yeMultichannel AV Preamps

PCB inogadzirisa home theatre inoita HDMI switching, audio decoding/rendering, bass management, room-processing uye multichannel digital-to-analog conversion pasina kungova ne high-power speaker amplifier stages inowanikwa muAV receiver. Izvi zvinoshandura zvinhu zvinokosheswa pakugadzira: ruzha rwakaderera rweanalog, clock integrity, DAC/output-stage matching, balanced line-level interfaces uye power-supply isolation zvinova zvakakosha kupfuura high-current speaker output.

Highleap Electronics inogadzira uye inounganidza maPCBA ekugadzira home theatre akagadzirwa nevatengi, anosanganisira mabhodhi makuru eHDMI/digital, mabhodhi eDSP/DAC, mabhodhi ekuburitsa analog ane ruzha rushoma uye mabhodhi ekudzora/network. Magadzirirwo eaudio, marezenisi, firmware uye calibration zvakaburitswa zvinoramba zvichidzorwa neOEM.

Zviri Mukati

1. Zvinhu Zvinokosheswa Pakugadzira neKugadzira PCB yeKey Home Theatre Processor

Mapurosesa eAV epamusoro anobatanidza HDMI inomhanya zvakanyanya neruzha rweanalog rwemazinga akaderera. Magadzirirwo ePCB anofanira kudzivirira mashandiro edhijitari/mavhidhiyo kuti asakanganisa ruzha uye kupatsanurwa kwenzira dzezvinobuda mumutsara.

  • Chikamu chekuchinja/kudzokorodza HDMI: Kuwanda kwezvinoiswa/zvinobuda, chinangwa cheTMDS/FRL, eARC uye mabasa ekudzokorora zvinofanirwa kutsanangurwa. Kurongeka kwekumhanya kwakanyanya kunogona kutevera PCB yeHDMI interface misimboti yekugadzira.
  • Magadzirirwo eOdhiyo DSP: Kugadzirisa manzwi, kugadzirisa bass, kunonoka, EQ uye kugadzirisa makamuri zvinoda mawachi ekusarudza uye nzira dzakawanda dzeI²S/TDM. Chikamu chedhijitari chinogona kuongororwa zvichienderana ne odhiyo DSP PCB kufunga.
  • Danho rekugadzira DAC/rekubuda nemazvo: Mareferensi eDAC, maop amps, mafirita uye madhiraivha ane balanced zvinofanira kuchengetedzwa kure nema converters ane ruzha uye mawachi eHDMI.
  • Kudzora wachi/kumhanya kwemhepo: Mawachi makuru eaudio, mawachi anobva kuHDMI uye asynchronous sample-rate conversion anofanira kuitwa zvichienderana nesilicon nefirmware yakasarudzwa. Kuiswa kwewachi uye routing yayo kunogonawo kuongororwa maererano ne dhizaini yePCB yekristaro oscillator nhungamiro.
  • Kupatsanura magetsi: Mitsetse yedhijitari, analog uye wachi ingangoda maregulator kana mafirita akasiyana. Kuisa pasi kunofanira kuitwa nemaune kwete kupatsanurwa pasina nzira yakatarwa yekudzokera.
  • Kuenzana kwechiteshi: Ma "multichannel analog outputs" anofanirwa kushandisa nzira dzakafanana dzekufambisa data, kuiswa kwezvikamu uye mazinga ekutarisa kuitira kuti kugadzirwa kusaunza shanduko ye "channel-to-channel".

Ndeupi musiyano mukuru wePCB pakati pe processor ye theatre yekumba neAV receiver?

Purosesa inonyanya kusimbisa kugadzirwa kwenzwi nechiratidzo zvine ruzha rwakaderera, nepo AVR ichibatanidzawo maamplifiers espeaker ane simba guru. Saka, processor inowanzo tarisa zvakanyanya pakushanda kweDAC, wachi uye analog-output uye nzvimbo shoma yebhodhi kune mapower stages ane simba guru.

Zvikamu zveanalog nedhijitari zvinoshandisa ndege dzepasi dzakasiyana zvachose here?

Kwete otomatiki. Nzira chaiyo yekudzika pasi inoenderana nekugadzirwa kwe converter, mareferensi e connector, chassis bonding uye nzira dzekudzoka kwesignal. Kupatsanura mapuraneti zvisina hanya kunogona kumanikidza kudzoka kwe high speed kana audio pakati pe discontinuities uye kuita kuti ruzha ruwedzere kuipa.

2. HDMI, DSP, DAC/ADC uye Kubatanidzwa Kwekubuda Kwakaenzanirana

Muchina wekugadzira ma "home theatre processor" i "multi-stage signal chain". HDMI audio inogamuchirwa kana kudzoserwa kuburikidza ne eARC, inogadziriswa muDSP, inoshandurwa kuita analog, inoseferwa uye inoendeswa kune ma "outputs" akawanda.

  • Chikamu cheHDMI transceiver: Kupinza/kuburitsa zvinomhanya zvakanyanya uye kudzora divi remagetsi zvinofanirwa kutevedzera kugadzirwa kunoshandiswa HDMI PCB kugadzira.
  • Mabhazi eDSP data: Ma I²S/TDM links anofanira kushandisa mawachi akafanana uye mapping yechiteshi. Iyo processor firmware inofanira kuenderana nehurongwa hwechinobatanidza/chekubuda.
  • Kurongeka kweDAC/ADC: Zvinhu zvinoshandisa analog, mareferensi, uye mafirita anobuda zvinofanirwa kushandisa nzira dzeruzha rushoma dzakatsanangurwa mu dhizaini yePCB yeaudio.
  • Zvakaringana zvinobuda: Madhiraivha emitsara yakasiyana-siyana, maconnector eXLR/RCA uye macircuits emute/relay anofanira kudzorwa nehukuru uye nemagetsi.
  • Network/kutonga: Ethernet/Wi-Fi/Bluetooth, display kana MCU control inofanira kuparadzaniswa nenzvimbo inobuda analog sezvinobvira.

Zvigadzirwa zvinogona kutsigira mafomati akawanda eaudio, asi mugadziri wechibvumirano anofanira kungoisa firmware inotenderwa neOEM chete uye kuyedza nzvimbo dzekutarisa kugadzirwa dzakatsanangurwa kune iyo rezenisi yekuvaka.

3. Kuungana kwePCBA isina ruzha rwakanyanya, Kutsvaga uye Kuongorora Zvikamu Zvakanyatsonaka

Mabhodhi epamusoro ekugadzirisa anogona kushandisa maDAC ane mutengo wakakwira, ma-op amps ane ruzha rushoma uye network dzisingashande dzakafanana. Kuchena kwekubatanidza uye kudzora kuchinjana kwedata kunogona kukosha kupfuura pabhodhi remultimedia.

  • Maitiro eOdhiyo PCBA: Highleap inogona kutsigira gungano rePCB reruzha rwakaderera matekiniki kunyangwe bhodhi iri preamplifier kwete power amplifier.
  • Kuwanikwa kwezvinhu kunodzorwa: MaDAC, ma-op amps, wachi, maregulator uye ma precision resistors/capacitors anofanirwa kutevedzera zvinotenderwa nevatengi. chikamu chekutsvaga list.
  • AOI: AOI muPCBA inogona kuona huwandu hweanalog-channel, kukosha kwezvikamu/nzvimbo uye kurongeka kweconnector.
  • X-ray: Mapakeji eHDMI/DSP BGA anogona kuongororwa ne X-ray kuongorora paidiwa.
  • Kuchena uye kudzora kuyerera kwemvura: Kubuda kwemvura kana zvasara zvakakomberedza ma "analog nodes" ane "high-impedance", ma "relay" kana ma "precision circuits" zvinofanirwa kutevedzera maitiro ekuchenesa/kuongorora akabvumiranwa.

Ndedzipi shanduko dzeBOM dzinogona kukanganisa mashandiro enzwi akayerwa?

Mienzaniso inowanzoonekwa inosanganisira zvikamu zveDAC reference, zvishandiso zvewachi, maop amps ane ruzha rushoma, mafirita anobuda, maanalog regulators uye zvikamu zvinogadzirisa kunyatsogadzirwa kwemagetsi. Kubvumidzwa kwekuchinjana kunofanirwa kufunga nezveruzha/kukanganiswa kwemagetsi kwete kungoenderana chete nepakeji/kukosha.
