DESCRIPTION:

The 5T915 2.5V differential (DDR) clock buffer is a user-selectable single-ended or differential input to fi ve differential outputs built on advanced

metal CMOS technology. The differential clock buffer fanout from a single

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

loading on the preceding driver and provides an effi cient clock distribution

network. The 5T915 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.

The 5T915 true or complementary outputs can be asynchronously

enabled/disabled. Multiple power and grounds reduce noise.
