Technical content
CFS 2914 is an adjustable inductor (clock extrac- tor coil) forMITEL MH89790 device. The MH89790 has a built in clock extraction cir- cuit, which creates a 2.048 MHz clock synchro- nized to the received E2 signal. The free-running frequency of the oscillator is controlled by an exter- nal tunable inductor. The inductor should be tuned to provide a frequency of 2.048 MHz± 200 Hz. Typical applications are:
- PBX or computer to T1/CEPT Digital trunks.
- High speed data link using T1/CEPT Digital trunks.
- TDM Multiplexers.
- ISDN Voice/Data. Filtran Limited 229 Colonnade Road, Nepean, Ontario, Canada.
