Legacy Device: Motorola MC145106
The ML145106 is a phase–locked loop (PLL) frequency synthesizer
constructed in CMOS on a single monolithic structure. This synthesizer
finds applications in such areas as AM radio, shortwave, amateur radio,
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 ML145106
has circuitry for a 10.24 MHz oscillator or may operate with an exter-
nal 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 program-
mable 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 fre-
quency 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.
