LM565/LM565C
Phase Locked Loop
General Description
The LM565 and LM565C are general purpose phase locked
loops containing a stable, highly linear voltage controlled os-
cillator for low distortion FM demodulation, and a double bal-
anced phase detector with good carrier suppression. The
VCO frequency is set with an external resistor and capacitor,
and a tuning range of 10:1 can be obtained with the same
capacitor.
The
characteristics
of
the
system — bandwidth, response speed, capture and pull in
range — may be adjusted over a wide range with an external
resistor and capacitor. The loop may be broken between the
VCO and the phase detector for insertion of a digital fre-
quency divider to obtain frequency multiplication.
The LM565H is specified for operation over the −55˚C to
+125˚C military temperature range. The LM565CN is speci-
fied for operation over the 0˚C to +70˚C temperature range.
