MC145162 dual phase–locked loop (PLL) frequency synthesizer SMD SOG16

This frequency synthesizer is for any product with a frequency operation at 60MHz 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–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.
