Description
The B9940L is a low-voltage clock distribution buffer with the
capability to select either a differential LVPECL- or an
LVCMOS/LVTTL-compatible input clock. The two clock
sources can be used to provide for a test clock as well as the
primary
LVCMOS/LVTTL compatible. The eighteen outputs are 2.5V or
3.3V compatible and can drive two series-terminated 50
transmission lines. With this capability the B9940L has an
effective fan-out of 1:36. Low output-to-output skews make the
B9940L an ideal clock distribution buffer for nested clock trees
in the most demanding of synchronous systems.
