ICS874005-04 Datasheet Pci Express Jitter Attenuator

Manufacturer: Integrated Device Technology

Overview: .. PCI EXPRESS™ JITTER ATTENUATOR ICS874005-04 GENERAL.

General Description

The ICS874005-04 is a high performance DiffIC S erential-to-LVDS Jitter Attenuator designed for use HiPerClockS™ in PCI Express systems.

In some PCI Express systems, such as those found in desktop PCs, the PCI Express clocks are generated from a low bandwidth, high phase noise PLL frequency synthesizer.

In these systems, a jitter attenuator may be required to attenuate high frequency random and deterministic jitter ponents from the PLL synthesizer and from the system board.

Key Features

  • Five differential LVDS output pairs.
  • One differential clock input.
  • Supports 100MHz, 125MHz, and 250MHz Serdes reference clocks.
  • CLK and nCLK supports the following input types: LVPECL, LVDS, LVHSTL, SSTL, HCSL.
  • Output frequency range: 98MHz - 320MHz.
  • Input frequency range: 98MHz - 128MHz.
  • PCI Express (2.5 Gb/S) and Gen 2 (5 Gb/s) jitter compliant.
  • RMS phase jitter @ 100MHz (1.875MHz.
  • 20MHz): 0.88ps (typical).
