ASM2P2309NZ  
Nine Output 3.3V Buffer  
Features  
Functional Description  
ꢀ
ꢀ
One-input to Nine-Output Buffer/Driver  
The ASM2P2309NZ is a low-cost buffer designed to  
distribute high-speed clocks in mobile PC systems and  
desktop PC systems with SDRAM support. The part has  
nine outputs, eight of which can be used to drive two  
DIMMs or four SO-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 133.33MHz.  
Supports two DIMMs or four SO-DIMMs with one  
additional output for feedback to an external or  
chipset PLL  
ꢀ
Low power consumption for mobile applications  
Less than 32mA at 66.6MHz with unloaded  
outputs  
ꢀ
ꢀ
ꢀ
ꢀ
1nS Input-Output delay  
Buffers all frequencies from DC to 133.33MHz  
Output-output skew less than 250pS  
Multiple VDD and VSS pins for noise and  
electromagnetic interference (EMI) reduction  
Space-saving 16-pin 150-mil SOIC Package  
3.3V operation  
The ASM2P2309NZ is designed for low EMI and power  
optimization. It has multiple VSS and VDD pins for noise  
optimization and consumes less than 32mA at 66.6MHz,  
making it ideal for the low-power requirements of mobile  
systems. It is available in an ultra-compact 150-mil 16-pin  
SOIC Package.
