DEVICE FOR CONTROLLING SYNCHRONIZATION OF DECT SYSTEM

摘要

PURPOSE: A device for controlling synchronization of DECT(Digital European Cordless Telephone) system is provided to fit synchronization among appropriate stations by supplying the standard clock for synchronization of each DECT interface card. CONSTITUTION: A device for controlling synchronization of DECT system includes a PLL circuit portion(200), a counter portion(300) and a controlling portion(400). The PLL circuit portion(200) synchronizes the standard signal for generating the synchronizing signal of DECT interfaces with the system clock and outputs it. The counter portion(300) counts the standard signal output from the PLL circuit portion(200) and generates the signal appropriate to a half of the DECT synchronization signal cycle. The controlling portion(400) receives the output signal of the counter portion(300) and the outer control signal and generates the synchronization signal for synchronizing many DECT interface cards.
