60 MHz and 85 MHz Universal

Programmable Dual PLL

Frequency Synthesizers

CMOS

The MC145162 is a dual phase鈥搇ocked loop (PLL) frequency synthesizer

especially designed for CT鈥? cordless phone applications worldwide. This

frequency synthesizer is also for any product with a frequency operation at

60 MHz or below.

The MC145162鈥? 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鈥? 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.
