A Serializer/Deserializer (SerDes) maviri emabhuraki anoshanda anowanzo shandiswa mukumhanyisa kutaurirana kutsiva kushomeka kwekupinza/kubuda.Aya mabhuroki anoshandura data pakati peserial data uye parallel interfaces munzira imwe neimwe.Izwi rekuti "SerDes" rinowanzo reva mainterface anoshandiswa mune akasiyana matekinoroji uye maapplication.Iko kushandiswa kwekutanga kweSerDes kupa data kutapurirana pamusoro pemutsara mumwechete kana adifferential pairkuti uderedze huwandu hweI/O pini uye zvinobatanidza.
Basa rekutanga reSerDes rinoumbwa nemabhuroki maviri anoshanda: iyo Parallel In Serial Out (PISO) block (aka Parallel-to-Serial converter) uye Serial In Parallel Out (SIPO) block (aka Serial-to-Parallel converter).Kune mana akasiyana maSerDes architectures: (1) Parallel wachi SerDes, (2) Embedded wachi SerDes, (3) 8b/10b SerDes, (4) Bit interleaved SerDes.
Iyo PISO (Parallel Input, Serial Output) chivharo chinowanzova newachi inopindirana, seti yemitsara yekuisa data, uye machira ekuisa data.Inogona kushandisa mukati kana kunzephase-locked loop (PLL)kuwedzera wachi iri kuuya inofananidzwa kusvika kune serial frequency.Iyo yakapfava fomu yePISO ine imwecheteshift registeriyo inogamuchira data rakafanana kamwe pawachi yakafanana, uye inoiburitsa kunze kune yakakwirira serial wachi mwero.Mashandisirwo anogona zvakare kushandisa akaviri-bufferedkunyoresa kunzvengakugadzikanapaunenge uchiendesa data pakati peachi domains.
Iyo SIPO (Serial Input, Parallel Output) block inowanzo ine yekugamuchira wachi inobuda, seti yemitsara yekuburitsa data uye inobuda data latches.Iyo wachi yekugamuchira inogona kunge yakadzoserwa kubva kune data neiyo serialkupora kwewachiunyanzvi.Nekudaro, SerDes iyo isingatumire wachi inoshandisa referensi wachi kuvhara iyo PLL kune chaiyo Tx frequency, kudzivirira yakaderera.harmonic frequencyaripo mudata stream.Iyo SIPO block inozopatsanura wachi inouya ichidzika kusvika pachiyero chakafanana.Mashandisirwo anowanzo ane marejista maviri akabatana seaviri buffer.Rimwe rejista rinoshandiswa kuvharisa murukova runotevedzana, uye rimwe racho rinoshandiswa kubata data redivi rinononoka, rakafanana.
Mamwe marudzi eSerDes anosanganisira encoding/decoding blocks.Chinangwa cheiyi encoding/decoding kazhinji kuisa kanenge manhamba miganhu pachiyero chekuchinja kwechiratidzo kubvumira kuti zvive nyore.kupora kwewachimuunogamuchira, kupakuumba, uye kupaDC chiyero.

Tsanangudzo yeDS90UB914A-Q1
Iyo DS90UB914A-Q1 mudziyo inopa FPD-Link III interface ine yakakwirira-kumhanya yekumberi chiteshi uye bidirectional control chiteshi chekufambisa kwedata pamusoro peiyo coaxial tambo kana maviri akasiyana.Iyo DS90UB914A-Q1 mudziyo unobatanidza kusaina kwakasiyana pane ese ari maviri-anomhanya-mberi chiteshi uye bidirectional control chiteshi nzira dzedata.Iyo deserializer inonangwa yekubatanidza pakati pemifananidzo uye vhidhiyo processors muECU (Electronic Control Unit).Ichi chishandiso chakanyatsokodzera kutyaira vhidhiyo data inoda kusvika ku12-bit pixel kudzika uye maviri masaini masaini pamwe nebidirectional control chiteshi bhazi.
Iyo deserializer inoratidzira multiplexer kubvumira sarudzo pakati pemapikicha maviri ekuisa, imwe inoshanda panguva.Yekutanga vhidhiyo yekufambisa inoshandura 10-bit kana 12-bit dhata kune imwechete yakakwira-kumhanya serial rukova, pamwe neyakaparadzana yakaderera latency bidirectional control chiteshi chekufambisa iyo inogamuchira ruzivo rwekutonga kubva kuI2C chiteshi uye yakazvimiririra yevhidhiyo isina nguva.
Kushandisa TI's yakamisikidzwa wachi tekinoroji inobvumira kujeka kuzere-duplex kutaurirana pamusoro peimwe mutsauko peya, inotakura asymmetrical-bidirectional control chiteshi ruzivo.Iyi single serial stream inorerutsa kuendesa dhata data bhazi pamusoro pePCB traces uye tambo nekubvisa matambudziko e skew pakati pe data rakafanana uye wachi nzira.Izvi zvinochengetedza zvakanyanya mutengo wesystem nekupfupisa nzira dzedata izvo zvinozodzikisa maseru ePCB, upamhi hwetambo, uye saizi yekubatanidza nemapini.Uye zvakare, iyo Deserializer yekupinza inopa inogadziriswa yakaenzana kutsiva kurasikirwa kubva kune midhiya pamusoro pemadaro marefu.Yemukati DC-yakaenzana encoding/decoding inoshandiswa kutsigira AC-yakabatana inobatana.
