VGA (Vhidhiyo Graphics Array) kureva, mavhidhiyo graphics array, ane high resolution, fast display rate, rich colours, etc. VGA interface haisi iyo yakajairwa chete yeCRT kuratidza zvishandiso, asiwo yakajairwa interface yeLcD liquid crystal display devices. , ine huwandu hwakawanda hwekushandisa.
VGA OUT PCB dhizaini kufunga
1. Iyo yakazara marongero, chigaro cheVGA sepedyo sezvinobvira kushanduko chip yakaiswa, edza kupfupisa VGA analog chiratidzo kurongeka.
2. Iyo decoupling capacitors yekushandura chip simba rekushandisa rinoda kuiswa sepedyo sezvinobvira kune mapini emagetsi ekugadzirisa chip.
3. VGA_R/G/B inoda kubatanidza 75ohm kudhonza-pasi resistor, kunyatsoita 1%;resistor inofanira kuiswa pedyo ne chip.
4. VGA_R / G / B kurongeka mutsara upamhi sezvo gobvu sezvinobvira, zvinokurudzirwa kuti kupfuura 12mil, uye kureba musiyano pakati pavo haafaniri kudarika 200mil.
5. VGA_R / G / B chiratidzo chinodiwa mukati mepakapatsanurwa pasi pekugadzirisa, packet ground alignment interval ye300mil kana pasi inofanira kuva nepasi pamusoro pegomba.
6. VGA_R / G / B chiratidzo chiri pedyo nedandemutande inofanira kuva pasi ndege, kwete simba ndege.
7. VGA_R / G / B zviratidzo zviri kure neLCD, DRAM nemimwe mitsetse yepamusoro-yekumhanya, inorambidzwa mumitsara yepamusoro-yepamusoro-soro iri pedyo nekugadzirisa mutsara;inorambidzwa mumitsetse yechiratidzo chepamusoro-soro pedyo negomba rekuisa;alignment usapfuure nenharaunda inductive;kure neRF zviratidzo uye zvishandiso;
8. VGA_HSYNC/VSYNC RC sefa inofanira kuiswa pedyo nechigaro cheVGA, kurongeka hakufaniri kudarika 6 Inch.
9. VGA chigaro zvose zviratidzo TVS tube inofanira kuiswa pedyo sezvinobvira kune chigaro chekubatanidza, chiratidzo chepamusoro: VGA chigaro → TVS → chip pin;ESD phenomenon, ESD ikozvino inofanira kutanga yapfuura nepakati peTVS mudziyo attenuation;TVS mudziyo kurongeka hauna chigutsa chakasara (Stub);TVS pasi pini vanokurudzirwa kuedza kuwedzera pasi pamusoro gomba, kanenge nechokwadi kuti maviri 0.4 * 0.2mm pamusoro buri, kusimbisa electrostatic discharge kugona.Simbisai electrostatic discharge capacity.
