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

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.

NOTES:

1. 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 150°C and a board trace length of 750 mils.
