MOTOROLA SEMICONDUCTOR TECHNICAL DATA Order this document by MC145190/D 1.1 GHz PLL Frequency Synthesizers MC145190 MC145191 Include On Board 64/65 Prescalers The MC145190 and MC145191 are single package synthesizers with serial interfaces capable of direct usage up to 1.1 GHz.

A special architecture makes these PLLs very easy to program because a byte oriented format is utilized.

Due to the patented BitGrabber™ registers, no address/steering bits are required for ra

MC145191 Features

* a single

* ended current source/sink phase detector output and a double

* ended phase detector output. Both phase detectors have linear transfer functions (no dead zones). The maximum current of the single

* ended phase detector output is determined by an external resistor tied fro
