Serializer / Deserializer (SerDes) yog ib khub ntawm kev ua haujlwm blocks feem ntau siv hauv kev sib txuas lus ceev kom them nyiaj rau cov tswv yim / tso tawm.Cov blocks no hloov cov ntaub ntawv ntawm cov ntaub ntawv serial thiab kev sib txuas sib txuas hauv txhua qhov kev coj.Lo lus "SerDes" feem ntau yog hais txog kev sib txuas siv hauv ntau yam thev naus laus zis thiab kev siv.Thawj qhov kev siv ntawm SerDes yog muab cov ntaub ntawv xa mus rau ib kab lossis ib qhosib txawv khubtxhawm rau txo tus naj npawb ntawm I / O pins thiab kev sib txuas.

 

Lub hauv paus SerDes muaj nuj nqi yog tsim los ntawm ob qho kev ua haujlwm blocks: Parallel In Serial Out (PISO) block (aka Parallel-to-Serial converter) thiab Serial In Parallel Out (SIPO) block (aka Serial-to-Parallel converter).Muaj 4 qhov sib txawv SerDes architectures: (1) Parallel moos SerDes, (2) Embedded moos SerDes, (3) 8b/10b SerDes, (4) Ntsis interleaved SerDes.

Lub PISO (Parallel Input, Serial Output) thaiv feem ntau muaj lub sijhawm sib npaug ntawm lub sijhawm nkag, txheej txheej ntawm cov ntaub ntawv nkag, thiab cov ntaub ntawv tawm tswv yim.Nws tuaj yeem siv sab hauv lossis sab nraudPhase-locked Loop (PLL)kom muab cov khoom xa mus rau lub sijhawm sib luag mus txog qhov zaus zaus.Daim ntawv yooj yim tshaj plaws ntawm PISO muaj ib qhopauv registeruas tau txais cov ntaub ntawv thaum uas tig mus ib zaug nyob rau hauv parallel moos, thiab hloov nws tawm ntawm lub siab dua serial moos tus nqi.Kev nqis tes ua kuj tseem yuav siv tau ib qhoob-bufferedsau npe kom zammetastabilitythaum hloov cov ntaub ntawv ntawm moos domains.

Lub SIPO (Serial Input, Parallel Output) thaiv feem ntau muaj cov khoom tso tawm moos, cov ntaub ntawv tso tawm kab thiab cov ntaub ntawv tso tawm.Lub moos txais yuav tau rov qab los ntawm cov ntaub ntawv los ntawm serialmoos rov qabtxheej txheem.Txawm li cas los xij, SerDes uas tsis xa lub moos siv lub moos siv los xauv lub PLL rau qhov tseeb Tx zaus, tsis txhob qis.harmonic zaustam sim no hauvcov ntaub ntawv ntws.Lub SIPO thaiv ces faib lub moos tuaj mus rau qhov sib npaug.Kev nqis tes ua feem ntau muaj ob daim ntawv sau npe txuas nrog ua ob qhov tsis sib xws.Ib daim ntawv teev npe yog siv los teev nyob rau hauv cov kwj serial, thiab lwm qhov yog siv los tuav cov ntaub ntawv rau qhov qeeb qeeb, sib npaug sab.

Qee hom SerDes muaj xws li encoding/decoding blocks.Lub hom phiaj ntawm qhov encoding / decoding no feem ntau yog muab qhov tsawg kawg ntawm kev cia siab rau ntawm tus nqi ntawm cov teeb liab hloov mus rau kev tso cai kom yooj yim dua.moos rov qabnyob rau hauv lub receiver, muabframing, thiab muabDC tshuav nyiaj li cas.

Kev piav qhia rau DS90UB914A-Q1

Lub DS90UB914A-Q1 ntaus ntawv muaj FPD-Link III interface nrog lub siab ceev rau pem hauv ntej channel thiab ob txoj kev tswj channel rau cov ntaub ntawv xa mus rau ib qho coaxial cable lossis ob khub sib txawv.Lub DS90UB914A-Q1 ntaus ntawv suav nrog cov teeb liab sib txawv ntawm ob qho tib si kev kub ceev rau pem hauv ntej channel thiab bidirectional tswj channel cov ntaub ntawv txoj hauv kev.Lub deserializer yog tsom rau kev sib txuas ntawm cov duab thiab cov txheej txheem video hauv ECU (Electronic Control Unit).Cov cuab yeej no yog qhov tsim nyog rau kev tsav tsheb cov ntaub ntawv video uas xav tau txog li 12-ntsis pixel qhov tob ntxiv rau ob lub teeb liab synchronization nrog rau kev tswj xyuas ob lub tsheb npav.

Lub deserializer nta ib tug multiplexer tso cai rau kev xaiv ntawm ob lub tswv yim imagers, ib tug nquag siv nyob rau hauv ib lub sij hawm.Thawj video thauj mus los hloov 10-ntsis lossis 12-ntsis cov ntaub ntawv mus rau ib qho kev ceev ceev serial kwj, nrog rau kev sib cais tsis tshua muaj latency bidirectional tswj channel thauj uas lees txais cov ntaub ntawv tswj los ntawm I2C chaw nres nkoj thiab tsis muaj kev ywj pheej ntawm lub sijhawm video blanking.

Siv TI's embedded moos thev naus laus zis tso cai rau kev sib txuas lus tag nrho-duplex hla ib khub sib txawv, nqa asymmetrical-bidirectional tswj cov ntaub ntawv xov xwm.Qhov no ib leeg serial kwj simplifies hloov ib tug dav cov ntaub ntawv tsheb npav hla PCB kab thiab cable los ntawm kev tshem tawm cov skew teeb meem ntawm parallel cov ntaub ntawv thiab moos paths.Qhov no txuag tau nyiaj ntau los ntawm kev nqaim cov ntaub ntawv txoj hauv kev uas ua rau txo qis PCB txheej, cable dav, thiab qhov sib txuas loj thiab pins.Tsis tas li ntawd, Deserializer inputs muab kev sib txig sib luag kom them nyiaj rau kev poob ntawm kev tshaj tawm ntev dua.Internal DC-balanced encoding / decoding yog siv los txhawb AC-coupled interconnects.
