Clocks & Timing

Overview

The IDT8T49N366I integrates low phase noise Frequency Translation / Synthesis and Jitter attenuation. It includes alarm and monitoring functions suitable for networking and communications applications. The device has three 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. A wide range of input reference clocks may be used as the source for the output frequency. Each PLL of IDT8T49N366I has three operating modes to support a very broad spectrum of applications: Frequency Synthesizer, High-Bandwidth Frequency Translator and Low-Bandwidth Frequency Translator.
