GENERAL DESCRIPTION

The ICS8344-01 is a low voltage, low skew fanout buffer and a member of the HiPerClockS™ family of High Performance Clock Solutions from ICS. The ICS8344-01 has two selectable clock inputs. The CLK0, nCLK0 and CLK1, nCLK1 pairs can accept most standard differential input levels.

FEATURES

• 24 LVCMOS outputs, 7Ω typical output impedance

• 2 selectable CLKx, nCLKx inputs

• CLK0, nCLK0 and CLK1, nCLK1 pairs can accept the

following input levels: LVDS, LVPECL, LVHSTL, SSTL,

HCSL

• Output frequency up to 250MHz

• Translates any single ended input signal to LVCMOS with

resistor bias on nCLK input

• Synchronous clock enable

• Output skew: 200 ps (maximum)

• Part-to-part skew: 900ps (maximum)

• Bank skew: 85ps (maximum)

• Propagation delay: 5ns (maximum)

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

• 0°C to 70°C ambient operating temperature

• Industrial temperature information available upon request
