CEPT CFS2914 CFS 2914 Adjustable Inductor CEPt Clock Extr. Coil. Through Hole Standard ................................................... 2-12 Typical applications are: CFS 2914 is an adjustable inductor (clock extractor coil) for MITEL MH89790 device. The MH89790 has a built in clock extraction circuit, which creates a 2.048 MHz clock synchronized to the received E2 signal. The free-running frequency of the oscillator is controlled by an external tunable inductor. The inductor should be tuned to provide a frequency of 2.048 MHz ± 200 Hz. • PBX or computer to T1/CEPT Digital trunks. • High speed data link using T1/CEPT Digital trunks. • TDM Multiplexers. • ISDN Voice/Data.
