General Description
The IDT8T49N105I 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 IDT8T49N105I has three operating modes to support a very broad spectrum of applications:
1) Frequency Synthesizer
Synthesizes output frequencies from a 16MHz - 40MHz
fundamental mode crystal.
Fractional feedback division is used, so there are no
requirements for any specific crystal frequency to produce the desired output frequency with a high degree o...
