NINE OUTPUT

3.3V CLOCK BUFFER

IDT2309NZ

FEATURES:

• 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

DESCRIPTION:

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.
