描述

The 8T49N281i has one 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 eight different output frequencies, ranging from 8kHz to 1GHz. Three of these frequencies are completely independent of each other and the inputs. The other five 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 8T49N282i (4-in/2-PLL/8-out) and the 8T49N283i (2-in/2-PLL/8-out).
