SEMICONDUCTOR TECHNICAL DATA
CMOS
The MC145106 is a phase–locked loop (PLL) frequency synthesizer
constructed in CMOS on a single monolithic structure. This synthesizer finds
applications in such areas as CB and FM transceivers. The device contains an
oscillator/amplifier, a 210 or 211 divider chain for the oscillator signal, a
programmable divider chain for the input signal, and a phase detector. The
MC145106 has circuitry for a 10.24 MHz oscillator or may operate with an
external signal. The circuit provides a 5.12 MHz output signal, which can be
used for frequency tripling. A 29 programmable divider divides the input signal
frequency for channel selection. The inputs to the programmable divider are
standard ground–to–supply binary signals. Pull–down resistors on these inputs
normally set these inputs to ground enabling these programmable inputs to be
controlled from a mechanical switch or electronic circuitry.
The phase detector may control a VCO and yields a high level signal when
input frequency is low, and a low level signal when input frequency is high. An
out–of–lock signal is provided from the on–chip lock detector with a “0” level for
the out–of–lock condition.

This device contains circuitry to protect the
inputs against damage due to high static voltages or electric fields; however, it is advised that
normal precautions be taken to avoid application
of any voltage higher than maximum rated
voltages to this high impedance circuit. For
proper operation it is recommended that Vin and
V
be constrained to the range VSS ≤ (Vin or
out
V
) ≤ VDD.
