Low-Voltage 60MHz 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 worldwide. 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.
