8T49N241 Overview
The 8T49N241 has one fractional-feedback PLL that can be used as a jitter attenuator and frequency translator. It is equipped with one integer and three fractional output dividers, allowing the generation of up to four different output frequencies, ranging from 8kHz to 1GHz. These frequencies are pletely independent of each other, the input reference frequencies, and the crystal reference frequency.
