有关 8T49N283 的资源
描述
The 8T49N283I 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 for the generation of up to eight different output frequencies, ranging from 8kHz to 1GHz. Four of these frequencies are completely independent of each other and the inputs. The other four are related frequencies. The eight outputs may select among LVPECL, LVDS, or LVCMOS output levels.
Renesas' third-generation Universal Frequency Translator family also includes the 8T49N281i (2-in/1-PLL/8-out) and the 8T49N282i (4-in/2-PLL/8-out).
