849N202CKI-008LF General Description

The 849N202I is a highly flexible FemtoClock® NG general purpose, low phase noise Universal Frequency Translator™ / Synthesizer with alarm and monitoring functions suitable for networking and communications applications. It is able to generate any output frequency in the 0.98MHz - 312.5MHz range and most output frequencies in the 312.5MHz - 1,300MHz range (see Table 3 for details). 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.

The 849N202I has three operating modes to support a very broad spectrum of applications.
