IDT8T49N203I

FemtoClock® NG Universal Frequency Translator IDT8T49N203I DATA SHEET General Description The IDT8T49N203I 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 IDT8T49N203I 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...
