DESCRIPTION:
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
differentialinput tofivedifferentialorsingle-endedoutputsreducesloadingon
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.

NOTES:
1. Stresses greater than those listed under ABSOLUTE MAXIMUM RATINGS may cause
permanent damage to the device. This is a stress rating only and functional operation
of the device at these or any other conditions above those indicated in the operational
sections of this specification is not implied. Exposure to absolute maximum rating
conditions for extended periods may affect reliability.
2. VDDQ and VDD internally operate independently. No power sequencing requirements
need to be met.
3. Not to exceed 3.6V.
