Abstract

En overføringsenhet over hvilken data utveksles mellom to kommunikasjonsenheter består hoved- sakelig av en taktregeneratorkrets (DPLL), en oscillator (V) og en koblingsenhet (SE) med et bufferminne (PS) og forbundet med en ankommende datastrøm (DAI) og en utgående data- strøm (DAO). Fremgangsmåten i henhold til opp- finnelsen består ved hjelp av taktregeneratorkretsen (DPLL) i fra den ankomne datastrøm (DAI) å danne en skrivetakt (Fl) til innlesing av data fra den ankommende datastrøm (DAI) i bufferminnet (PS). Videre blir det ved hjelp av en oscillator (V) dannet en lesetakt (FO) til lesing av de i bufferminnet (PS) lagrede data for dannelse av den utgående data- strøm (DAO). Endelig blir lesetakten (FO) dertil benyttet som referansefrekvens i taktregenerator- kretsen (DPLL).
