概要
説明
The 8536-01 is a low skew, high performance 1-to-6 Selectable Crystal, Single-Ended, or Differential Input-to-3.3V, 2.5V LVPECL Fanout Buffer and a member of the HiPerClockS™ family of High Performance Clock Solutions from IDT. The 8536-01 has selectable crystal, single ended or differential clock inputs. The single ended clock input accepts LVCMOS or LVTTL input levels and translates them to LVPECL levels. The CLK1, nCLK1 pair can accept most standard differential input 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 8536-01 ideal for those applications demanding well defined performance and repeatability.
