General Description
MC145162 General Description
The MC145162 is a dual phaselocked loop (PLL) frequency synthesizer especially designed for CT1 cordless phone applications worldwide. This frequency synthesizer is also for any product with a frequency operation at 60 MHz or below.
The MC1451621 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 CT1 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.
