Overview

Description

The IDT8T49N222I is a highly flexible FemtoClock® NG general purpose, low phase noise Frequency Translator / Synthesizer with alarm and monitoring functions suitable for networking and communications applications. It is able to generate any output frequency in the 7.68MHz to 1200MHz range. A wide range of input reference clocks and a range of low-cost fundamental mode crystal frequencies may be used as the source for the output frequency.
