DESCRIPTION:
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.
