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 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 Commercial and Industrial temperature parts are available ASM2P2309NZ 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.
