CY2314ANZ  
14 Output, 3.3V SDRAM Buffer for  
Desktop PCs with 3 DIMMs  
Functional Description  
Features  
• One input to 14 output buffer/driver  
• Supports up to three SDRAM DIMMs  
• Two additional outputs for feedback  
• Serial interface for output control  
• Low skew outputs  
The CY2314ANZ is a 3.3V buffer designed to distribute  
high-speed clocks in desktop PC applications. The part has 14  
outputs, 12 of which can be used to drive up to three SDRAM  
DIMMs, and the remaining can be used for external feedback  
to a PLL. The device operates at 3.3V and outputs can run up  
to 100 MHz, thus making it compatible with Pentium® II pro-  
cessors. The CY2314ANZ can be used in conjunction with the  
CY2280, CY2281, CY2282 or similar clock synthesizer for a  
complete Pentium II motherboard solution.  
• Up to 100-MHz operation  
• Multiple VDD and VSS pins for noise reduction  
• Dedicated OE pin for testing  
• Low EMI outputs  
The CY2314ANZ also includes a serial interface which can  
enable or disable each output clock. On power-up, all output  
clocks are enabled. A separate Output Enable pin facilitates  
testing on ATE.  
• 28-pin SOIC (300-mil) package  
• 3.3V operation
