CD4046BMS
CMOS Micropower Phase Locked Loop
Description
CD4046BMS CMOS Micropower Phase-Locked Loop (PLL)
consists of a low power linear voltage-controlled oscillator (VCO)
and two different phase comparators having a common signal-
input amplifier and a common comparator input. A 5.2V zener
diode is provided for supply regulation if necessary.
The CD4046BMS is supplied in these 16-lead outline packages:
VCO Section
The VCO requires one external capacitor C1 and one or two
external resistors (R1 or R1 and R2). Resistor R1 and capacitor
C1 determine the frequency range of the VCO and resistor R2
enables the VCO to have a frequency offset if required. The high
input impedance (10
12
) of the VCO simplifies the design of low
pass filters by permitting the designer a wide choice of resistor-
to-capacitor ratios. In order not to load the low-pass filter, a
source-follower output of the VCO input voltage is provided at ter-
minal 10 (DEMODULATED OUTPUT). If this terminal is used, a
load resistor (RS) of 10k
or more should be connected from
this terminal to VSS. If unused this terminal should be left open.
The VCO can be connected either directly or through frequency
dividers to the comparator input of the phase comparators. A full
CMOS logic swing is available at the output of the VCO and
allows direct coupling to CMOS frequency dividers such as the
Intersil CD4024, CD4018, CD4020, CD4029, and CD4050. One
or more CD4018 (Preset Table Divide-By-N Counter) or CD4029
(Presettable Up/Down Counter) or CD4029 (Presettable Divide-
by-N Counter) or CD4029 (Presettable Up/Down Counter), or
CD4059A (Programmable Divide-by “N” Counter), together with
the CD4046BMS (Phase-Locked Loop) can be used to build a
micropower low-frequency synthesizer. A logic 0 on the INHIBIT
input “enables” the VCO and the source follower, while a logic 1
“turns off” both to minimize stand-by power consumption.
