The IDT5T915 2.5V differential (DDR) clock buffer is a user-selectable single-ended or differential input to five differential outputs built on advanced metal CMOS technology. The differential clock buffer fanout from a single or differential input to five differential or single-ended outputs reduces loading on the preceding driver and provides an efficient clock distribution network. The IDT5T915 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 IDT5T915 true or complementary outputs can be asynchronously enabled/disabled. Multiple power and grounds reduce noise.
