8543BGILFT - Renesas Electronics

Description: The 8543I is a low skew, high performance 1-to-4 Differential-to-LVDS Clock Fanout Buffer. Utilizing Low Voltage Differential Signaling (LVDS) the 8543I provides a low power, low noise, solution for distributing clock signals over controlled impedances of 100Ω. The 8543I 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
