GENERAL DESCRIPTION

FEATURES

The ICS83940D is a low skew, 1-to-18 LVPECL-

• 18 LVCMOS/LVTTL outputs

ICS

to-LVCMOS/LVTTL Fanout Buffer and a member

• Selectable LVCMOS_CLK or LVPECL clock inputs

HiPerClockS™

of the HiPerClockS™ family of High Performance

Clock Solutions from ICS. The ICS83940D has

two selectable clock inputs. The PCLK, nPCLK

• PCLK, nPCLK supports the following input types:

LVPECL, CML, SSTL

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 50Ω series or parallel terminated transmission lines.

• LVCMOS_CLK accepts the following input levels:

LVCMOS or LVTTL

• Maximum output frequency: 250MHz

• Output skew: 150ps (maximum)

The ICS83940D 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

ICS83940D ideal for those clock distribution applications

demanding well defined performance and repeatability.

• Part to part skew: 750ps (maximum)

• Additive phase jitter, RMS: < 0.03ps (typical)

• Full 3.3V and 2.5V or mixed 3.3V core, 2.5V output

supply modes

• 0°C to 70°C ambient operating temperature

• Lead-Free package available

• Pin compatible with the MPC940L
