描述
The 8T349316 is a 2.5V differential clock buffer with sixteen LVDS outputs. The fanout from a differential input to the sixteen LVDS outputs reduces loading on the preceding driver and provides an efficient clock distribution network. The 8T349316 can act as a translator from a differential HSTL, LVPECL, CML, or LVDS input to LVDS output signals. A single-ended 3.3V, 2.5V LVCMOS/LVTTL input can also be used to translate to LVDS outputs. The redundant input capability allows for an asynchronous changeover from a primary clock source to a secondary clock source. Selectable reference inputs are controlled by SEL. The 8T349316 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. The extended temperature range supports wireless infrastructure, telecommunication, and networking end equipment requirements.
