841N254B, NG Crystal-to-LVDS/ HCSL Clock Synthesizer

FemtoClock® NG Crystal-to-LVDS/ HCSL Clock Synthesizer 841N254B Datasheet Description The 841N254B is a 4-output clock synthesizer designed for S-RI

Features

* ▪ Fourth generation FemtoClock® (NG) technology ▪ Selectable 250MHz, 156.25MHz, 125MHz or 100MHz output clock synthesized from a 25MHz fundamental mode crystal ▪ Four differential clock outputs (two LVDS and two HCSL outputs) ▪ Crystal interface designed for 25MHz, parallel resonant crystal ▪ RMS ph

Applications

* The device generates four copies of a selectable 250MHz, 156.25MHz, 125MHz or 100MHz clock signal with excellent phase jitter performance.
The four outputs are organized in two banks of two LVDS and two HCSL ouputs.
The device uses IDT’s fourth generation FemtoClock® NG technology for an optimum of
