DATA SHEET

General Description

Features

TheICS83940DI isalow 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.

• Eighteen LVCMOS/LVTTL outputs

• Selectable LVCMOS_CLK or LVPECL clock inputs

• PCLK, nPCLK pair can accept the following differential input

levels: LVPECL, CML, SSTL

• LVCMOS_CLK supports the following input types: LVCMOS or

LVTTL

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.

• Maximum output frequency: 250MHz

• Output skew: 150ps (maximum)

• Part-to-part skew: 750ps (maximum)

• Operating supply modes:

• Core/Output

3.3V/3.3V

3.3V/2.5V

2.5V/2.5V
