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 V
DD
and V
SS
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 150C and a board trace length of 750 mils.
