8T49N488 Overview
The 8T49N488 is a quad PLL with FemtoClock® NG technology, it integrates low phase noise Frequency Translator / Synthesizer, Jitter attenuation, and with alarm and monitoring functions suitable for networking and munications 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...
