General Description
The ICS83940DI is a low skew, 1-to-18 LVPECL- to-LVCMOS/LVTTL Fanout Buffer. The ICS83940DI 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 50 series or parallel terminated transmission lines.
