CY29943  
2.5V or 3.3V 200-MHz 1:18 Clock Distribution Buffer  
Features  
Description  
• 200-MHz clock support  
• 2.5V or 3.3V operation  
• LVPECL clock input  
The CY29943 is a low-voltage 200-MHz clock distribution  
buffer with an LVPECL-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 50series or parallel terminated transmission lines. For  
series terminated transmission line, each output can drive one  
or two traces giving the device an effective fanout of 1:36. Low  
output-to-output skews make the CY29943 an ideal clock  
distribution buffer for nested clock trees in the most  
demanding of synchronous systems.  
• LVCMOS-/LVTTL-compatible inputs  
• 18 clock outputs: drive up to 36 clock lines  
• 200 ps max. output-to-output skew  
• Output Enable control  
• Pin compatible with MPC942P  
• Available in Industrial and Commercial  
• 32-pin LQFP package
