Description
The PI6C4911510 is a high-performance low-skew 1-to-10 LVPECL
fanout buffer. The PI6C4911510 features two selectable dif-
ferential clock inputs and translates to ten LVPECL outputs.
The CLK inputs accept LVPECL, LVDS, CML and SSTL signals.
PI6C4911510 is ideal for clock distribution applications such as
providing fanout for low noise SaRonix-eCera oscillators.

Phase Noise and Additive Jitter
Output phase noise (Dark Blue) vs Input Phase noise (light blue)
Additive jitter is calculated at ~27fs RMS (12kHz to 20MHz). Additive jitter = √(Output jitter2 - Input jitter2)
