PCI Express™ Jitter Attenuator

ICS874001I-05

DATA SHEET

General Description

Features

The ICS874001I-05 is a high performance Jitter Attenuator designed

for use 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

components from the PLL synthesizer and from the system board.

The ICS874001I-05 has a bandwidth of 6MHz with <1dB peaking,

easily meeting PCI Express Gen2 PLL requirements.

The ICS874001I-05 uses IDT’s 3^RDGeneration FemtoClock^®

PLL technology to achieve the lowest possible phase noise. The

device is packaged in a small 20-pin TSSOP package, making it

ideal for use in space constrained applications such as PCI Express

add-in cards.

• One differential LVDS output pair

• One differential clock input

• CLK, nCLK supports the following input levels: LVPECL, LVDS,

LVHSTL, SSTL, HCSL

• Input frequency range: 98MHz to 128MHz

• Output frequency range: 98MHz to 640MHz

• VCO range: 490MHz - 640MHz

• Cycle-to-cycle jitter: 50ps (maximum)

• Full 3.3V operating supply

• PCI Express (2.5Gb/s) and Gen 2 (5 Gb/s) jitter compliant

• -40°C to 85°C ambient operating temperature

• Available in lead-free (RoHS 6) package
