ICS83940I-01

Integrated

Circuit

Systems, Inc.

SKEW, 1-TO-18

LVPECL-TO-LVCMOS / LVTTL FANOUT

BUFFER

FEATURES

GENERAL DESCRIPTION

• 18 LVCMOS/LVTTL outputs, 23Ω typical output impedance

• Selectable LVCMOS_CLK or LVPECL clock inputs

The ICS83940I-01 is a low skew, 1-to-18

ICS

LVPECL-to-LVCMOS/LVTTL Fanout Buffer and a

member of the HiPerClockS™ family of High Per-

formance Clock Solutions from ICS. The

ICS83940I-01 has two selectable clock inputs.

HiPerClockS™

• LVCMOS_CLK supports the following input types:

LVCMOS or LVTTL

The PCLK, nPCLK pair can accept LVPECL, CML or SSTL

input levels. The single ended clock input accepts LVCMOS

or LVTTL input levels. The low impedance LVCMOS/LVTTL

outputs are designed to drive 50Ω series or parallel termi-

nated transmission lines.The effective fanout can be increased

from 18 to 36 by utilizing the ability of the outputs to drive two

series terminated lines.

• PCLK, nPCLK supports the following input types:

LVPECL, CML, SSTL

• Maximum output frequency: 250MHz

• Output skew: 150ps (maximum)

• Part-to-part skew: 750ps (maximum)

• Full 3.3V, 2.5V or mixed 3.3V, 2.5V supply modes

• -40°C to 85°C ambient operating temperature

The ICS83940I-01 is characterized at full 3.3V, full 2.5V and

mixed 3.3V input and 2.5V output operating supply modes. Guar-

anteed output and part-to-part skew characteristics make the

ICS83940I-01 ideal for those clock distribution applications de-

manding well defined performance and repeatability.

• Pin compatible with the MPC940L in single supply

applications
