DATA SHEET
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.
The ICS83940DI is characterized at full 3.3V and 2.5V or mixed 3.3V
core, 2.5V output operating supply modes. Guaranteed output and
part-to-part skew characteristics make the ICS83940DI ideal for
those clock distribution applications demanding well defined
performance and repeatability.
