T1 / DS1 CFS2575 CFS 2575 Adjustable Inductor CEPT Output Transformer Surface Mount SMD-6 ........................................................ 2-11 CFS 2575 is an adjustable inductor (clock extractor coil) for MITEL MH89760 device. Typical applications are: The MH89760 has a built in clock extraction circuit, which creates a 1.544 MHz clock synchronized to the received DS1 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 1.544 MHz ± 200 Hz. • PBX or computer to T1/CEPT Digital trunks. • High speed data link using T1/CEPT Digital Trunk. • TDM Multiplexers. • ISDN Voice/Data.
