The IDT2309NZ is a low-cost buffer designed to distribute high-speed clocks in mobile PC systems and desktop PC systems with SDRAM support.
The IDT2309NZ is a low-power clock buffer/driver featuring one input and nine outputs. Eight of these outputs are designed to drive two DIMMs or four SO-DIMMs, while the ninth output provides feedback to an external or chipset PLL. The device operates at 3.3V with frequencies up to 133.33MHz.
