SEMICONDUCTOR TECHNICAL DATA
Low-Voltage 60 MHz Universal
Programmable Dual PLL
Frequency Synthesizer
CMOS
The MC145165 is a low–voltage dual phase–locked loop (PLL) frequency
synthesizer especially designed for CT–1 cordless phone applications world-
wide. This frequency synthesizer is also for any product with a frequency
operation at 60 MHz or below.
This chip is suitable for any portable RF products which use two 1.2 V
chargeable Ni–Cd batteries. The feature of low operating voltage can reduce
the current consumption and the cost of the portable RF products by reducing
the number of batteries used.
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. All of the functions and features of the MC145165 are fully compatible
with the MC145162.
