GENERAL DESCRIPTION

The ICS85408 is a low skew, high performance 1-to-8 Differential-to-LVDS Clock Distribution Chip and a member of the HiPerClockS™ family of High Performance Clock Solutions from ICS. The ICS85408 CLK, nCLK pair can accept most differential input levels and translates them to 3.3V LVDS output levels. Utilizing Low Voltage Differential Signaling (LVDS), the ICS85408 provides a low power, low noise, low skew, point-to-point solution for distributing LVDS clock signals.

FEATURES

• 8 Differential LVDS outputs

• CLK, nCLK pair can accept the following differential input levels: LVPECL, LVDS, LVHSTL, SSTL, HCSL

• Maximum output frequency: 700MHz

• Translates any differential input signal (LVPECL, LVHSTL, SSTL, HCSL) to LVDS levels without external bias networks

• Translates any single-ended input signal to LVDS with resistor bias on nCLK input

• Multiple output enable inputs for disabling unused outputs in reduced fanout applications

• Output skew: 50ps (maximum)

• Part-to-part skew: 550ps (maximum)

• Propagation delay: 2.4ns (maximum)

• 3.3V operating supply

• 0°C to 70°C ambient operating temperature

• Lead-Free package RoHS compliant
