IDT2309NZ NINE OUTPUT 3.3V CLOCK BUFFER COMMERCIAL AND INDUSTRIAL TEMPERATURE RANGES NINE OUTPUT IDT2309NZ 3.3V CLOCK BUFFER FEATURES: DESCRIPTION: One input to nine output buffer/driver The IDT2309NZ is a low-cost buffer designed to distribute high-speed Supports two DIMMs or four SO-DIMMs with one additional clocks in mobile PC systems and desktop PC systems with SDRAM output for feedback to an external or chipset PLL support. This part has nine outputs, eight of which can be used to drive Low power consumption for mobile applications: less than two DIMMs or four SO-DIMMs, and the remaining can be used for external 32mA at 66.6MHz with unloaded outputs feedback to a PLL. The IDT2309NZ operates at 3.3V and outputs can run 8.7ns input-output delay up to 133.33MHz Buffers all frequencies from DC to 133.33MHz The IDT2309NZ is designed for low EMI and power optimization. It has Output-output skew < 250ps multiple VDD and VSS pins for noise optimization and consumes less than Multiple VDD and VSS pins for noise and EMI reduction 32mA at 66.6MHz, making it ideal for the low power requirements of mobile 3.3V operation systems.

Stresses greater than those listed under ABSOLUTE MAXIMUM RATINGS may cause SOIC/ TSSOP permanent damage to the device. This is a stress rating only and functional operation TOP VIEW 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.
