Description
The CY29942 is a low-voltage 200-MHz clock distribution
buffer with an LVCMOS or LVTTL compatible input clock. All
other control inputs are LVCMOS/LVTTL compatible. The
eighteen outputs are 2.5V or 3.3V LVCMOS or LVTTL
compatible and can drive 50
series or parallel terminated
transmission lines. For series terminated transmission lines,
each output can drive one or two traces giving the devices an
effective fanout of 1:36. Low output-to-output skews make the
CY29942 an ideal clock distribution buffer for nested clock
trees in the most demanding of synchronous systems.
