60 MHz and 85 MHz Universal
Programmable Dual PLL
Frequency Synthesizers
CMOS
The MC145162 is a dual phase–locked loop (PLL) frequency synthesizer
especially designed for CT–1 cordless phone applications worldwide. This
frequency synthesizer is also for any product with a frequency operation at
60 MHz or below.
The MC145162–1 is a high frequency derivative of the MC145162, for
products with operating frequencies of 85 MHz or below.
The device features fully programmable receive, transmit, reference, and
auxiliary reference counters accessed through an MCU serial interface. This
feature allows this device to operate in any CT–1 cordless phone application.
The device consists of two independent phase detectors for transmit and
receive loops. A common reference oscillator, driving two independent
reference frequency counters, provides independent reference frequencies for
transmit and receive loops. The auxiliary reference counter allows the user to
select an additional reference frequency for receive and transmit loops if
required.
