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.
