8T49N281 Description
The 8T49N281 has a fractional-feedback PLL that can be used as a jitter attenuator or frequency translator. 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. Three of these frequencies are pletely independent of each other and the inputs.
