Description
The PI6C4853111 is a high-performance low-skew 1-to-10 LVPECL
fanout buffer. The PI6C4853111 features two selectable differential
clock inputs and translates to ten LVPECL outputs.The CLK inputs
accept LVPECL, LVDS, CML and SSTLsignals.
PI6C4853111 is ideal for clock distribution applications such as
providing fanout for low noise SaRonix-eCera oscillators.
