ASM2P2309NZ June 2005 rev 0.2 Nine Output 3.3V Buffer Features Functional Description One-input to Nine-Output Buffer/Driver 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 1nS Input-Output delay 3.3V and outputs can run up to 133.33 MHz. Buffers all frequencies from DC to 133.33 MHz Output-output skew less than 250pS The ASM2P2309NZ is designed for low EMI and power 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, Space-saving 16-pin 150-mil SOIC Package making it ideal for the low-power requirements of mobile 3.3V operation systems. It is available in an ultra-compact 150-mil 16-pin Commercial and Industrial temperature parts are SOIC package. available Block Diagram Alliance Semiconductor 2575, Augustine Drive • Santa Clara, CA • Tel: 408.855.4900 • Fax: 408.855.4999 • www.alsc.com Notice: The information in this document is subject to change without notice.
