TheoryofOperation
TheSFP‐BHDVXCTransceiverisaSmallFormFactorPluggable(SFP)modulewithcoaxialinterface.HD‐BNC
connectorsareusedtointerfacethemodulewith75Ωcoaxialcables.
TheSFP‐BHDVXCTransceiverwilldrivethedifferentialTD±inputstoitsTXcoaxialoutputifTX_DISinputislow
andSoftTx_Disableislow(Status/Controlregisterbit6).
TheslewrateoftheSFP‐BHDVXC‐0000‐LoutputisconfigurablethroughtheSERIALCONFIGINTERFACEvia
SoftRate_Selectandshallbeconfiguredbasedonthetransmittedsignalstandardtoensurecompliancywith
SMPTEspecification.Atpowerup,thedefaultconfiguredslewrateiscompliantwithHD/3G‐SDIsignal.
BecausethedefaultslewrateisforHD‐SDI&3G‐SDI,thehostshoulddetectifthemodulegetsswappedvia
MOD_DEF0.IfmoduleisreplacedorhotswappedwhiledrivinganSD‐SDIsignal,thenewmodulewillhavethe
wrongslewrateanditwillrequirereconfiguration.TheslewrateoftheSDIoutputsoftheSFP‐BHDVXC‐0000‐
RisautomaticallyconfiguredbythereclockerandiscompliantwithSMPTEspecification.
TheSFP‐BHDVXCTransceiverautomaticallyequalizedthereceivedsignal(RX)forthecablelossandretimes
(reclockerversiononly)serialdigitalvideodataconformingtotheSMPTE424M,292Mand259M.Withouta
validsignaldetected,theLOSoutputisactive(open‐drain).
TheSFP‐BHDVXCTransceivermodulehasaserialinterfacethroughwhichanEEPROMcontainingtheSERIAL
IDENTIFICATIONcanberead.Throughthesameserialinterface,diagnosticmonitoringisprovidedviathe
SERIALCONFIGINTERFACEgivingtheopportunitytoreadthetemperature,thesupplyvoltage,theLOSstatus
andallreclockerfeatures.

GettingStarted
InitialInspection
Immediatelyuponreceipt,inspecttheshippingcontainerfordamage.Thecontainershouldberetaineduntil
theshipmenthasbeencheckedforcompletenessandtheequipmenthasbeencheckedmechanicallyand

OtherConsiderations
VideoOptimization
TheSocietyofMotionPictureandTelevisionEngineers,orSMPTE,isaleaderinthedevelopmentofstandards
forfilm,television,andothervideo.TheSerialDigitalInterfaceorSDI,wasstandardizedbySMPTEfor
broadcastqualitydigitalvideotransmission.Otherstandardsevolvedfromthisoriginalstandard,defining
Enhanced,High‐definition(HD),3G‐SDI(1080p)andUltraHigh‐definition(UHD),or4Kvideo(2160p).
Tohelpensureerror‐freetransmission,thestandardsincludeadatascrambler/descramblertocreateahigh
densityoftransitionsintheserialdata,makingiteasierforthereceivertomaintaintiming.Wherean
encodingmethodsuchas8B‐10Bensuresaminimalsequentialrunofallonesorzeros,itdoessoatthecost
ofa25%increaseinbandwidthrequirements.Thescrambler/descramblermethoddoesnotrequirethis,but
asaresulttherearecertaincombinationsofscramblerstateandthenextdatabitstobescrambledthatresult
inasequenceofuptotwentyconsecutiveonesorzeros.Thesesequencesarereferredtoaspathological
conditions,andarepresentinspecificshadesofpinkorgrey.
ThesepathologicalconditionsmaycreateerrorsintransmissionthroughtypicalACcoupledoptics,orany
otherACcoupledinterface.VideoEnhancedorSMPTECompliantopticsaredesignedtoacceptthese
pathologicalconditions,allowingthelongersequencesofonesorzerostopasswithouterror.
SFPMSACompliance
TheSFPMulti‐SourceAgreement(MSA)isanagreementthatwasdraftedamongcompetingmanufacturersof
SFPopticalmodules.TheSFFCommitteewasformedtooverseethecreationandmaintenanceofthese
agreementsincludingtheSFPMSAdesignatedasINF‐8074i.Thisagreementdescribesamutuallyagreedupon
standardfortheformandfunctionofSFPmodules.However,notallSFPsproducedareMSAcompliant.The
MSAprovidesforatransceiver(TX/RX)pinout.OtherindustriessuchasbroadcasthadtheneedfordualTX
anddualRXSFPforunidirectionalapplicationssuchasvideo.Naturally,anon‐MSAstandardwasintroduced
