Description
The PI6C48535-11B is a high-performance low jitter and low-skew
LVPECL fanout buffer. PI6C48535-11B features selectable of
single-ended clock or crystal inputs and translates to four LVPECL
outputs.The CLK input accepts LVCMOS or LVTTL signals.The
outputs are synchronized with input clock during asynchronous as-
sertion /deassertion of CLK_EN pin.PI6C48535-11B is ideal for
crystal or LVCMOS/LVTTL to LVPECL translation.Typical clock
translation and distribution applications are data-communications
and telecommunications.
