描述
The 83940D is a low skew, 1-to-18 LVPECL-to- LVCMOS/LVTTL Fanout Buffer. The 83940D has two selectable clock inputs. The PCLK, nPCLK pair can accept LVPECL, CML, or SSTL input levels. The LVCMOS_CLK can accept LVCMOS or LVTTL input levels. The low impedance LVCMOS/LVTTL outputs are designed to drive 50Ω series or parallel terminated transmission lines. The 83940D is characterized at full 3.3V and 2.5V or mixed3.3V core, 2.5V output operating supply modes. Guaranteed output and part-to-part skew characteristics make the 83940D ideal for those clock distribution applications demanding well defined performance and repeatability.
