FemtoClock® NG Ultra-Performance Jitter Attenuator
8T49N240
Datasheet
Description
The 8T49N240 is a fractional-feedback single channel jitter attenuator with frequency translation. It is equipped with three integer and one fractional output dividers, allowing the generation of up to four different output frequencies, ranging from 8kHz to 867MHz. These frequencies are completely independent of the input reference frequencies and the crystal reference frequency. The outputs may select among LVPECL, LVDS, HCSL, or LVCMOS output levels.
The 8T49N240 accepts up to two differential or single-ended input clocks and a fundamental-mode crystal input. The internal PLL can lock to either of the input reference clocks or just to the crystal to behave as a frequency synthesizer.
