DESCRIPTION:

The IDT5T9306 2.5V differential clock buffer is a user-selectable

differential input to six LVDS outputs. The fanout from a differential input

to six LVDS outputs reduces loading on the preceding driver and provides

an efficient clock distribution network. The IDT5T9306 can act as a

translator from a differential HSTL, eHSTL, LVEPECL (2.5V), LVPECL

(3.3V), CML, or LVDS input to LVDS outputs. A single-ended 3.3V / 2.5V

LVTTL input can also be used to translate to LVDS outputs. The redundant

input capability allows for an asynchronous change-over from a primary

clock source to a secondary clock source. Selectable reference inputs are

controlled by SEL.

The IDT5T9306 outputs can be asynchronously enabled/disabled. When

disabled, the outputs will drive to the value selected by the GL pin. Multiple

power and grounds reduce noise.
