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.
