Product Description

2.1 Overview

The PMB 2341 is a monolithic, low power, high performance phase-locked-loop (PLL)

frequency synthesizer. It is primarily designed to be used for very stable low noise LO

signals in mobile communication systems such as GSM, PCN (GSM 1800), PCS and

PDC. The wide range of divider rations also allows application in modern analog sys-

tems.
