CY29940  
2.5V or 3.3V, 200-MHz, 1:18 Clock Distribution Buffer  
Features  
Description  
• 200-MHz clock support  
The CY29940 is a low-voltage 200-MHz clock distribution buff-  
er with the capability to select either a differential LVPECL or  
a LVCMOS/LVTTL compatible input clock. The two clock  
sources can be used to provide for a test clock as well as the  
primary system clock. All other control inputs are LVC-  
MOS/LVTTL compatible. The eighteen outputs are 2.5V or  
3.3V LVCMOS/LVTTL compatible and can drive 50series or  
parallel terminated transmission lines. For series terminated  
transmission lines, each output can drive one or two traces  
giving the device an effective fanout of 1:36. Low out-  
put-to-output skews make the CY29940 an ideal clock distri-  
bution buffer for nested clock trees in the most demanding of  
synchronous systems.  
• LVPECL or LVCMOS/LVTTL clock input  
• LVCMOS/LVTTL compatible inputs  
• 18 clock outputs: drive up to 36 clock lines  
• 60 ps typical output-to-output skew  
• Dual or single supply operation:  
— 3.3V core and 3.3V outputs  
— 3.3V core and 2.5V outputs  
— 2.5V core and 2.5V outputs  
• Pin compatible with MPC940L, MPC9109  
• Available in Commercial and Industrial temperature  
• 32-pin LQFP package
