IDT8T49N445I

FemtoClock® NG QUAD Universal Frequency Translator IDT8T49N445I DATA SHEET General Description The IDT8T49N445I is a quad PLL with FemtoClock® NG technology. The IDT8T49N445I integrates low phase noise Frequency Translation / Synthesizer and jitter attenuation. It includes alarm and monitoring functions suitable for networking and communications applications. The device has four fully independent PLLs, each PLL 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 may be used as the source for the output frequency. Each PLL of IDT8T49N445I has three operating modes to support a very broad spectrum of applications: 1) Frequency Synthesizer Synthesizes output frequencies from an external reference clock REFCLK. Fractional feedback division is used, so there are no requirements for any specific input reference clock frequency to prod...
