Description
The PI6C4911504-03 is a high performance fanout buffer device
which supports up to 1.5GHz frequency. PI6C4911504-03 fea-
tures selectable single-ended clock or crystal inputs and trans-
lates to four LVPECL outputs. The outputs are synchronized
with input clock during asynchronous assertion /deassertion of
CLK_EN pin. PI6C4911504-03 is ideal for crystal or LVCMOS/
LVTTL to LVPECL translation. Typical clock translation and
distribution applications are data-communications and telecom-
munications.This device is ideal for systems that need to distrib-
ute low jitter clock signals to multiple destinations.
Applications
ÎÎNetworking systems including switches and Routers
ÎÎHigh frequency backplane based computing and telecom
platforms
