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.
