8543

The 8543 is a low skew, high performance 1-to-4 Differential-to-LVDS Clock Fanout Buffer. Utilizing Low Voltage Differential Signaling (LVDS) the 8543 provides a low power, low noise, solution for distributing clock signals over controlled impedances of 100?. The 8543 has two selectable clock inputs. The CLK, nCLK pair can accept most standard differential input levels. The PCLK, nPCLK pair can accept LVPECL, CML, or SSTL input levels. The clock 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 8543 ideal for those applications demanding well defined performance and repeatability.
