Overview

Product 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 assertion/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.
