Kugadzira PCB yeVideo Scaler yekushandura nekugadzirisa mafomati

PCB yekuongorora vhidhiyo inogamuchira vhidhiyo, inoigadzirisa uye inoburitsa resolution yakasiyana, nguva, fomati yemavara kana chiyero chefuremu zvichienderana nekugadzirwa kwechigadzirwa. Magadzirirwo epamusoro-soro anogona kusanganisira kubvisa ma "deinterlacing", "frame buffering", "color-space conversion", "picture-in-picture" kana "OSD". Kusiyana ne "HDMI repeater" iri nyore, bhodhi rekuongorora rine "digital processing" yakakura, "memory bandwidth" uye "clock-domain management" pamwe chete ne "external high-speed video interfaces".

Highleap Electronics inogadzira uye inounganidza maPCBA ekugadzira mavhidhiyo akagadzirwa nevatengi. Isu tinotsigira kugadzirwa kwe multilayer/HDI kana zvichidikanwa, BGA processor uye memory assembly, HDMI interface components, programming, testing uye functional functional yevhidhiyo inotsanangurwa nevatengi.

1. Zvinhu Zvinokosheswa pakugadzira nekugadzira PCB yeKey Video Scaler

Magadzirirwo e scaler anofanira kutsanangurwa usati wasarudza stack-up nekuti input bandwidth, output bandwidth, frame buffer uye processor package zvinosarudza routing density uye memory requirements.

• Tsanangudzo yevhidhiyo yekuisa/kuburitsa: Taura nzvimbo dzinotangira uye nzvimbo dzinoshandiswa kudhiraivha, magadzirirwo edata, uye nzira dzedata. Kune magadzirirwo eHDMI, ruzivo rwenzira nerunobatanidza runogona kuongororwa uchishandisa PCB yeHDMI interface misimboti.
• Sarudzo yeScaler/processor: Mapurogiramu evhidhiyo akazvipira, FPGAs kana kuti maSoC ane zvinodiwa zvakasiyana zvekurangarira, simba uye firmware. Pakeji yekugadzira inofanira kukiya kugadziriswa kwemuchina chaiwo.
• DDR furemu buffer: Kuchinja frame-rate, kubvisa ma frame kana kugadzirisa multi-frame zvinogona kuda external DDR. Memory topology uye kureba kunofanirwa kutevedzera. high-speed PCB dhizaini zvinodiwa.
• Kudzora wachi-domain: Maawa ekupinda, ekugadzirisa uye ekubudisa anogona kusiyana. Mareferensi ekufambisa, PLL supply filtering uye reset timing zvinofanirwa kunge zvakagadzikana uye zvichidzorwa ne revision control.
• Kudzorwa impedance: HDMI, memory nedzimwe serial link dzinofanira kushandisa serial stack-up yakaburitswa ine nzira imwechete yekugadzira seyakagadzirwa. PCB yekudzora impedance Kubudisa.
• Dhizaini yekupisa: Kugadzirisa mavhidhiyo uye DDR zvinogona kugadzira kupisa kunogara kuripo. Kupararira kwemhangura, mavias uye heatsink/enclosure interfaces zvinofanirwa kusimbiswa pamutengo wepamusoro wekugadzirisa.

Sei bhodhi re scaler richiwanzoda memory yakawanda kupfuura HDMI switch?

Switch inonyanya kuendesa rwizi ruripo, nepo scaler inogona kuchengetedza chikamu kana furemu yese kuti igadzirise saizi, kushandura frame-rate, kubvisa tambo kana kubatanidza. Izvi zvinogadzira zvimwe zvinodiwa zveDDR bandwidth, simba uye marongerwo.

FPGA yakakodzera rini paPCB yekuyera vhidhiyo?

FPGA inobatsira kana chigadzirwa chichida mapipeline akagadzirwa, mafomati asina kujairika, latency yakaderera kana kugadziriswa kwemastream akawanda. IC kana SoC yakatsaurirwa inogona kunge iri nani kana mabasa ayo akavakirwa mukati achienderana nezvinodiwa zvechigadzirwa.

2. Kugadzirisa Mavhidhiyo, Frame Buffer, OSD uye HDMI Interface Integration

Bhodhi rekuyera iketani yechiratidzo inobva kumagumo kusvika kumagumo. Purosesa ingangofanira kugamuchira HDMI, kutsanangura nguva uye metadata, kupinda muDDR, kuyera kana kushandura mufananidzo, kufukidza OSD uye kutumirazve zvinobuda.

• Nzira yekugamuchira vhidhiyo/yekutumira: Zvishandiso zveHDMI zvinogamuchira uye zvinotumira zvinofanirwa kuiswa kuti zvideredze kureba kwechiteshi chekunze chinomhanya zvakanyanya. HDMI PCB kugadzirwa kwakakosha pazvinobatanidza zvese.
• Kurongeka kwebuffer yefuremu: DDR inofanira kuramba iri pedyo ne processor ine mareferensi anoramba achienderera mberi uye topology inotenderwa nevatengesi.
• OSD/ndangariro yekudzora: MaUI overlay, maLUT kana maframe buffers angada imwe flash kana memory; firmware uye density yemidziyo zvinofanirwa kusungirirwa kuPCB revision.
• Kuchinja ruvara nenguva: YCbCr/RGB, chroma, bit depth uye timedevice mabasa ekugadzirisa anotsanangurwa nevatengi. Fekitori inofanira kuongorora mashandiro akarongwa pane kugadzira nzira dzekuyedza.
• Kuburitswa/kuburitswa kwenzwi: Kana HDMI odhiyo ikapasiswa, yakabviswa kana kuiswazve, interface nefirmware zvinofanirwa kuiswa muchikamu chekuedza kugadzirwa.

Mapurogiramu ekare evhidhiyo anoratidza kuti scaling, deinterlacing, OSD uye dual HDMI outputs zvinogona kushanda pamwe chete mumudziyo mumwe chete, asi magadzirirwo echigadzirwa chazvino anofanira kutevedzera silicon yakasarudzwa nemutengi uye seti yemaficha anotsigirwa.

3. Kuungana kweBGA/DDR, Kutsvaga Zvikamu uye Kuongorora

MaPCBA ekuongorora mavhidhiyo anowanzo shandisa maBGA makuru, DDR memory, QFN HDMI devices uye mapower rails akawanda. Kuongororwa kwemaitiro ekutanga kwakakosha usati waisa huwandu hwese hwekuongorora.

• Kuungana kweBGA: Highleap inogona kushandisa Musangano weBGA PCB zvinodzora zveSoCs/FPGAs uye ndangariro.
• Kuwanikwa kwemari kwakatenderwa: Mapurosesa, DDR, HDMI vagamuchiri/vatumidziri, mawachi uye maPMIC anofanirwa kutevedzera zvakaburitswa chikamu chekutsvaga mutemo.
• AOI: AOI muPCBA inosimbisa mapassive anooneka, maconnector uye huwandu hwezvikamu.
• X-ray: Majoini akavanzwa eBGA/LGA anogona kuongororwa ne X-ray kuongorora uko kunodiwa nehurongwa hwemhando yepamusoro.
• Kuungana kweThermal-interface: Mapedhi eheatsink, maclip kana ma enclosure heat spreaders anofanira kudzorwa nehukuru kuitira kuti processor isadzvanyirirwe zvakanyanya kana kusiiwa nemhepo isina chinhu.

Chii chinofanira kusimbiswa nechinhu chekutanga che scaler kunze kwekusungirirwa?

Simbisa kuti processor yakarongwa sei, DDR inopasa bvunzo yekurangarira yemutengi, makiyi ekupinda/kubuda kwevhidhiyo, shanduko yechiyero chechinangwa inoshanda, maconnector anoenderana ne enclosure uye tembiricha ye processor inoramba iri mukati memuganhu wakatsanangurwa nemutengi.

4. Kuedza Kunoshanda Kwekugadzirisa, Nguva uye Kushandura Vhidhiyo

Chiyereso chinofanira kuyedzwa nemafomati anozivikanwa ekupinda uye mafomati anotarisirwa ekubuda. Kungoratidza mufananidzo pane imwe resolution hazviratidzi kuti nzira yekugadzirisa inofamba sei.

• Kufukidzwa kwemafomu ekuisa: Shandisa zvigadziro zvinotsanangurwa nevatengi, mitengo yekuzorodza uye mafomati emavara.
• Nguva yekubuda: Iva nechokwadi chekuti scaler inogadzira nguva inotarisirwa yekunyura uye chinongedzo chakasimba.
• Nzvimbo yekutarisa kugadzirisa mifananidzo: Shandisa pateni inozivikanwa kusimbisa chiyero, crop, aspect ratio kana maitiro eOSD.
• Ruzha/metadata: Tarisa kuti zvakaburitswa kana kuti zvakaburitswa here kana kuti zvakaiswa mudhizaini yakaburitswa.
• FCT yekugadzira: Highleap inogona kuita kushanda kushanda nemagetsi anotenderwa, madhiraivha/anoongorora, firmware uye mitemo yekupasa/kukundikana.

5. Kuburitswa kweZvigadzirwa uye Data reRFQ reKugadzira PCB yeVideo Scaler

Kuyera kunofanira kunge kwakavakirwa pane chinangwa chaicho chekupinda/kubuda uye chekugadzirisa nekuti huwandu hwememory, FPGA/SoC package, huwandu hwema layer uye michina yekuyedza zvinoenderana nemafomati anodiwa.

• Pakeji yePCB: Kuunganidza zvinhu, kupindira, HDI/kuburikidza nekuvaka kana zvichidikanwa uye ruzivo rwekupisa/makanika.
• Kugadzira magadzirirwo: Scaler/FPGA/SoC, DDR, flash, HDMI receiver/transmitter uye maMPN ewachi.
• Zvinodiwa pavhidhiyo: Maitiro ekuisa, maitiro ekuburitsa, maitiro ekuyera/kuchekerera/maitiro eOSD uye nzira yekuteerera.
• Kuronga: FPGA bitstream, firmware, configuration uye revision mapping.
• Kushanda bvunzo: Manyuko emapatani, mamodhi evhidhiyo, sinki/muchina wekuongorora zvinobuda uye miganhu yekugamuchirwa inoyerwa.

Rondedzero yeRFQ yekugadzirwa

• Mafaira ekugadzira nekugadzira maPCB akaburitswa
• Processor/FPGA/DDR BOM
• Tsanangudzo yemodhi yekuisa/kuburitsa yeHDMI
• Zvinotaurwa nezvekupisa uye zvemakanika
• Firmware/bitstream uye mafaira ekugadzirisa
• Maitiro ekuyedza mashandiro evhidhiyo
• Muenzaniso, chiyero chekutanga kana huwandu hunodzokororwa
• Zvinodiwa pakurongedza uye kutevedza zvinodiwa

Highleap Electronics inotsigira kugadzirwa kwePCB uye kugadzirwa kwezvigadzirwa zvePCB zvekuwedzera mavhidhiyo zvakagadzirwa nevatengi uye kushandura mafomati. Zvinotaurwa zvemhando yemufananidzo wechigadzirwa chapedzwa uye kutevedzera zvinodiwa zvinoramba zviri muOEM kunze kwekunge zvataurwa pachena.
