8534I-13 - Block Diagram
説明
The 8534I-13 is a low skew, high performance 1-to-4 Crystal Oscillator/LVCMOS-to-3.3V LVPECL/ LVCMOS fanout buffer and a member of the HiPerClockS™ family of High Performance Clock Solutions from IDT. The 8534I-13 has selectable single ended clock or crystal inputs. The single ended clock input accepts LVCMOS or LVTTL input levels and translate them to 3.3V LVPECL levels. The output enable is internally synchronized to eliminate runt pulses on the outputs during asynchronous assertion/deassertion of the clock enable pin. Guaranteed output and part-to-part skew characteristics make the 8534I-13 ideal for those applications demanding well defined performance and repeatability.
