CFS 2914 is an adjustable inductor (clock extrac-
tor coil) for MITEL 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.
