NINE OUTPUT

3.3V CLOCK BUFFER

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

32mA at 66.6MHz, making it ideal for the low power requirements of mobile

systems.
