Mumidziyo yeEthernet, kana PHY chip yakabatana neRJ, network transformer inowanzowedzerwa.Iyo yepakati pombi yemamwe network matransformer yakadzikwa.Mamwe akabatanidzwa kune magetsi, uye kukosha kwesimba kunogona kuve kwakasiyana, kusanganisira 3.3V, 2.5V, uye 1.8V.Zvino nzira yekubatanidza iyo yepakati pombi (PHY kupera) yetransformer?

A. Sei mamwe mapombi epakati akabatana nesimba?Vamwe vakaiswa pasi?

Izvi zvinonyanya kutsanangurwa neUTP port driver mhando yePHY chip inoshandiswa.Mhando dzekutyaira dzakakamurwa kuita: voltage drive uye ikozvino dhiraivha.Batanidza magetsi paunenge uchityaira nevoltage;batanidza capacitor pasi paunenge uchityaira neyazvino.Naizvozvo, nzira yekubatanidza yepombi yepakati inodyidzana neiyo UTP port drive mhando yePHY chip.Panguva imwecheteyo, ndapota tarisa kune dhatabheti uye referensi dhizaini yechip.

Ongorora: Kana iyo yepakati pombi yakabatana zvisizvo, network port ichave isina kugadzikana zvakanyanya kana kuvharika.

B. Sei yakabatanidzwa kune imwe voltage yakasiyana kana yakabatanidzwa kune magetsi?

Izvi zvinotemerwawo neiyo UTP port level inotsanangurwa muPHY chip data inoshandiswa.Chiyero chinofanira kunge chakabatana nemagetsi anoenderana, kureva kuti, kana iri 1.8v, ichadhonzwa kusvika ku1.8v, kana iri 3.3v, ichadhonzwa kusvika ku3.3v.

Basa repakati pombi yeLAN transformer:

1. Deredza iyo yakajairwa modhi ikozvino uye yakajairika mode voltage patambo nekupa yakaderera impedance nzira yekudzoka kune yakajairika modhi ruzha pamutsara wekusiyanisa;

2. Kune mamwe ma transceivers, ipa DC bias voltage kana sosi yemagetsi.

Iyo yakabatanidzwa RJ yakajairika mode kudzvinyirira inogona kuve nani, uye parasitic paramita zvakare haina kukanganiswa;saka, kunyange zvazvo mutengo wacho wakanyanya kukwirira, unofarirwawo zvikuru nekuda kwekubatanidzwa kwayo kwepamusoro, nzvimbo duku, kudzvinyirira maitiro, parasitic parameters nezvimwe zvakanakira.Mauya.

Ndeipi basa renetwork transformer?Haukwanise kunhonga here?

Tichingotaura, inogona kushanda zvakajairika isina kubatanidza network inoshandura uye yakanangana neRJ.Nekudaro, kureba kwekutapurirana kuchave kushoma, uye zvakare ichakanganiswa kana yabatanidzwa kune network chiteshi cheimwe nhanho.Uye kupindira kwekunze kune chip zvakare kukuru.Kana iyo network network yakabatana, inonyanya kushandiswa padanho rekubatanidza chiratidzo.1. Simbisa chiratidzo kuti chinhambwe chekufambisa chiende kure;2. Isolate the chip end kubva kunze, wedzera anti-kupindira kugona, uye kuwedzera kuchengetedzwa kwechip (zvakadai semheni inorova);3. Kana yakabatana nemazinga akasiyana (akadai seMamwe PHY machipi ari 2.5V, uye mamwe machipi ePHY ari 3.3V), hazvizokanganisa zvishandiso zveumwe neumwe.
Kazhinji, network transformer inonyanya kuita mabasa ekufambisa kwemasaini, impedance kuenzanisa, kugadzirisa waveform, kudzvanywa kwechiratidzo uye kuparadzaniswa kwemagetsi.
