CFS 2575 is an adjustable inductor (clock extrac-

tor coil) for MITEL MH89760 device.

The MH89760 has a built in clock extraction cir-

cuit, which creates a 1.544 MHz clock synchro-

nized to the received DS1 signal. The free-running

frequency of the oscillator is controlled by an ex-

ternal tunable inductor. The inductor should be

tuned to provide a frequency of 1.544 MHz

± 200

Hz.

Typical applications are:

•

PBX or computer to T1/CEPT Digital trunks.

•

High speed data link using T1/CEPT Digital

Trunk.

•

TDM Multiplexers.

•

ISDN Voice/Data.
