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.
