DESCRIPTION:

The 5T905 2.5V single data rate (SDR) clock buffer is a user-selectable

single-ended or differential input to fi ve single-ended outputs buffer built on

advanced metal CMOS technology. The SDR clock buffer fanout from a

single or differential input to fi ve single-ended outputs reduces the loading

on the preceding driver and provides an effi cient clock distribution network.

The IDT5T905 can act as a translator from a differential HSTL, eHSTL,

1.8V/2.5V LVTTL, LVEPECL, or single-ended 1.8V/2.5V LVTTL input to

HSTL, eHSTL, 1.8V/2.5V LVTTL outputs. Selectable interface is controlled

by 3-level input signals that may be hard-wired to appropriate high-mid-low

levels. Multiple power and grounds reduce noise.
