I-Serializer/Deserializer (i-SerDes) yipere yeebhloko ezisebenzayo ezisetyenziswa ngokuqhelekileyo kunxibelelwano lwesantya esiphezulu ukuhlawula igalelo/imveliso elinganiselweyo.Ezi bloko ziguqula idatha phakathi kwedatha ye-serial kunye nojongano oluhambelanayo kwicala ngalinye.Igama elithi "SerDes" libhekisa ngokubanzi kunxibelelwano olusetyenziswa kwiitekhnoloji ezahlukeneyo kunye nokusetyenziswa.Usetyenziso oluphambili lwe-SerDes kukubonelela ngokuhanjiswa kwedatha kumgca omnye okanye aisibini esahlukileyoukuze kuncitshiswe inani lezikhonkwane ze-I/O kunye neziqhagamshelo.
Umsebenzi osisiseko we-SerDes wenziwa ngeebhloko ezimbini ezisebenzayo: ibhloko yeParallel In Serial Out (PISO) (aka Parallel-to-Serial converter) kunye ne-Serial In Parallel Out (SIPO) block (aka Serial-to-Parallel converter).Kukho ii-SerDes ezahlukeneyo ze-architectures: (1) Iwotshi enxuseneyo i-SerDes, (2) I-SerDes yewotshi eEmbedded, (3) 8b/10b SerDes, (4) i-Bit interleaved SerDes.
I-PISO (Igalelo Elinxuseneyo, Igalelo Lothotho) ibhloko iqhele ukuba negalelo lewotshi enxuseneyo, iseti yelayini yongeniso lwedatha, kunye neentambo zedatha yokufaka.Inokusebenzisa yangaphakathi okanye yangaphandleI-loop evaliweyo ngesigaba (PLL)ukuphinda-phinda ikloko ehambelanayo engenayo ukuya kumaza othotho.Eyona ndlela ilula yePISO inomnyeirejista yeshiftiefumana idata enxuseneyo kanye ngewotshi nganye enxuseneyo, kwaye iyisuse ngesantya esiphezulu sewotshi.Umiliselo lunokuthi lusebenzise akabini-bufferedbhalisa ukuze uphepheukuqinaxa uhambisa idatha phakathi kweendawo zewotshi.
I-SIPO (i-Serial Input, i-Parallel Output) ibhloko idla ngokufumana i-clock output, isethi yemigca yokuphuma kwedatha kunye neentambo zedatha yemveliso.Iwotshi yokufumana inokuba ifunyenwe kwidatha ngothothoukubuyisela iwotshiubuchule.Nangona kunjalo, ii-SerDes ezingathumeli iwotshi yokusetyenziswa kwewotshi ukutshixa i-PLL kwi-Tx frequency echanekileyo, ukuthintela ukwehla.Izandi ze-harmonicekhoyo kwiumjelo wedatha.Ibhloko ye-SIPO ke yahlula-hlula iwotshi engenayo phantsi kwireyithi ehambelanayo.Uzalisekiso lukholisa ukuba neerejista ezimbini eziqhagamshelwe njengesithinteli esiphindiweyo.Enye irejista isetyenziselwa ukuwohloka kuthotho lomlambo, kwaye enye isetyenziselwa ukubamba idatha yecala elicothayo, elinxuseneyo.
Ezinye iindidi zee-SerDes ziquka ii-encoding/decoding blocks.Injongo yolu guqulelo lwekhowudi/ukuguqulwa kwekhowudi kukubeka noko imida yamanani kumyinge wotshintsho lomqondiso ukuvumela lula.ukubuyisela iwotshikumamkeli, ukunikaukwenza isakhelo, kunye nokubonelelaIbhalansi yeDC.

Inkcazelo ye-DS90UB914A-Q1
Isixhobo se-DS90UB914A-Q1 sinikezela nge-FPD-Link III i-interface kunye neshaneli ehamba phambili ehamba phambili kunye ne-bidirectional channel control control for transmission data over a single coaxial cable or differential pair.Isixhobo se-DS90UB914A-Q1 sibandakanya ukubonakaliswa okwahlukileyo kuzo zombini iitshaneli ezihamba phambili ezihamba phambili kunye neendlela zokulawula i-bidirectional channel data.I-deserializer ijoliswe kuqhagamshelo phakathi kwemifanekiso kunye nabaqhubekekisi bevidiyo kwi-ECU (iYunithi yoLawulo loMbane).Esi sixhobo sikufanele ukuqhuba idatha yevidiyo efuna ukuya kuthi ga kwi-12-bit ye-pixel ubunzulu kunye nemiqondiso emibini yongqamaniso kunye nebhasi yesitishi sokulawula i-bidirectional.
I-deserializer ifaka i-multiplexer ukuvumela ukhetho phakathi kwemifanekiso emibini yokufaka, enye iyasebenza ngexesha.Uthutho lwevidiyo oluphambili luguqula i-10-bit okanye i-12-bit yedatha kwi-serial ye-serial stream enye enesantya esiphezulu, kunye ne-low latency ephantsi yolawulo lwe-bidirectional yothutho lwesiteshi esamkela ulwazi lolawulo oluvela kwi-port ye-I2C kwaye izimeleyo kwixesha levidiyo elingenanto.
Ukusebenzisa itekhnoloji yewotshi efakwe kwi-TI ivumela unxibelelwano olupheleleyo lwe-duplex olucacileyo ngaphezulu kwesibini esihlukeneyo, ephethe ulwazi lwetshaneli yokulawula i-asymmetrical-bidirectional.Lo mjelo omnye we-serial wenza kube lula ukudlulisa ibhasi yedatha ebanzi ngaphezulu kwetrayiti ye-PCB kunye nentambo ngokususa iingxaki ze-skew phakathi kwedatha ehambelanayo kunye neendlela zewotshi.Oku kusindisa kakhulu iindleko zenkqubo ngokunciphisa iindlela zedatha ezithi zinciphise iileya zePCB, ububanzi bentambo, kunye nobukhulu bokudibanisa kunye nezikhonkwane.Ukongeza, amagalelo e-Deserializer abonelela ngokulinganisa okuguquguqukayo ukuhlawulela ilahleko evela kumajelo eendaba kumgama omde.I-DC-balanced encoding/decoding isetyenziselwa ukuxhasa i-AC-coupled interconnects.
