Additional preview pages of the 841N254B datasheet.

The 841N254B is a 4-output clock synthesizer designed for S-RIO 1.3 and 2.0 reference clock applications.

The device generates four copies of a selectable 250MHz, 156.25MHz, 125MHz or 100MHz clock signal with excellent phase jitter performance.

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 phase jitter at 156.25MHz, using a 25MHz crystal (1MHz - 20MHz): 0.27ps (typical).
RMS phase jitter at 156.25MHz, using a 25MHz crystal (12kHz - 20MHz): 0.32ps (typical).
