PI6C48535-11
3.3V Low Skew 1-to-4
Crystal/LVCMOS to LVPECL Fanout Buffer
Description
The PI6C48535-11 is a high-performance low-skew LVPECL
fanout buffer. PI6C48535-11 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. PI6C48535-11 is ideal for crystal or
LVCMOS/LVTTL to LVPECL translation. Typical clock transla-
tion and distribution applications are data-communications and
telecommunications.
