IDT2309NZ NINE OUTPUT 3.3V CLOCK BUFFER COMMERCIAL AND INDUSTRIAL TEMPERATURE RANGES IDT2309NZ NINE OUTPUT 3.3V CLOCK BUFFER FEATURES: 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 * 8.7ns input-output delay * Buffers all frequencies from DC to 133.33MHz * Output-output skew < 250ps * Multiple VDD and VSS pins for noise and EMI reduction * 3.3V operation * High drive capability * Available in SOIC and TSSOP packages The IDT2309NZ is a low-cost buffer designed to distribute high-speed clocks in mobile PC systems and desktop PC systems with SDRAM support. This 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 IDT2309NZ operates at 3.3V and outputs can run up to 133.33MHz The IDT2309NZ is designed for low EMI and power optimization. It has multiple VDD and VSS pins for noise optimization and consumes less than 32mA at 66.6MHz, making it ideal for the low power requirements of mobile systems.

Stresses greater than those listed under ABSOLUTE MAXIMUM RATINGS may cause permanent damage to the device. This is a stress rating only and functional operation of the device at these or any other conditions above those indicated in the operational sections of this specification is not implied. Exposure to absolute maximum rating conditions for extended periods may affect reliability. 2. The input and output negative-voltage ratings may be exceeded if the input and output clamp-current ratings are observed. 3. The maximum package power dissipation is calculated using a junction temperature of 150C and a board trace length of 750 mils.
