LVPECL-to-LVCMOS/LVTTL Fanout Buffer

ICS83940DI

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.
