8T49N287 Overview
The 8T49N287 has two independent, fractional-feedback PLLs that can be used as jitter attenuators and frequency translators. It is equipped with six integer and two fractional output dividers, allowing the generation of up to 8 different output frequencies, ranging from 8kHz to 1GHz. Four of these frequencies are pletely independent of each other and the inputs.
8T49N287 Key Features
