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