Resources for 83940
Description
The 83940 is a low skew, 1-to-18 LVPECL-to-LVCMOS/ LVTTL Fanout Buffer. The 83940 has twoselectable 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 83940 is characterized at full 3.3V, full 2.5V and mixed 3.3V input and 2.5V output operating supply modes. Guaranteed output and part-to-part skew characteristics make the 83940 ideal for those clock distribution applications demanding well defined performance and repeatability.
