Functional Description
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.
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.
