Functional Description
The CY29942 is a low voltage clock distribution buffer with an
LVCMOS or LVTTL compatible clock input. The output enable
control input is LVCMOS/LVTTL compatible. The eighteen
outputs are 2.5 V or 3.3 V LVCMOS or LVTTL compatible,
operate up to 200 MHz, and can drive 50 series or parallel
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.
