PRELIMINARY

DIFFERENTIAL-TO-0.7V DIFFERENTIAL

PCI EXPRESS™ JITTER ATTENUATOR

ICS871002I-02

GENERAL DESCRIPTION

Features

The ICS871002I-02 is a high performance Jitter

• Two 0.7V differential output pairs

• One differential clock input

ICS

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

HiPerClockS™

• CLK and nCLK supports the following input types: LVPECL,

LVDS, LVHSTL, SSTL, HCSL

• Output frequency range: 98MHz - 640MHz

• Input frequency range: 98MHz - 128MHz

• VCO range: 490MHz - 640MHz

• Cycle-to-cycle jitter: 20ps (typical)

• 3.3V operating supply

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

ICS871002I-02 has two PLL bandwidth modes: 350kHz and

2000kHz. The 350kHz mode will provide maximum jitter

attenuation, but with higher PLL tracking skew and spread

spectrum modulation from the motherboard synthesizer may

be attenuated. The 2000kHz bandwidth provides the best

tracking skew and will pass most spread profiles, but the jitter

attenuation will not be as good as the lower bandwidth modes.

The ICS871002I-02 can be set for different modes using the

F_SELx pins as shown in Table 3C.

• Two bandwidth modes allow the system designer to make

jitter attenuation/tracking skew design trade-offs

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

• Available in both standard (RoHS 5) and lead-free (RoHS 6)

packages

The ICS871002I-02 uses IDT 3^rdGeneration FemtoClock^TMPLL

technology to achieve the lowest possible phase noise. The

device is packaged in a small 20 Lead TSSOP package, making

it ideal for use in space constrained applications such as PCI

Express add-in cards.
