Overview

Description

The 85408 is a low skew, high performance 1-to-8 Differential-to-LVDS Clock Distribution Chip from IDT. The 85408 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 85408 provides a low power, low noise, low skew, point-to-point solution for distributing LVDS clock signals. Guaranteed output and part-to-part skew specifications make the 85408 ideal for those applications demanding well defined performance and repeatability.

Features

  • Eight differential LVDS output pairs
  • CLK/nCLK can accept the following differential input levels: LVPECL, LVDS, LVHSTL, HCSL, SSTL
  • 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
  • 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
  • Available in lead-free (RoHS 6) package
