GENERAL DESCRIPTION

Features

The ICS874004 is a high performance Differential- • (4) Differential LVDS output pairs

ICS

to-LVDS Jitter Attenuator designed for use in PCI

• (1) Differential clock input

HiPerClockS™

Express™ systems. In some PCI Express™

systems, such as those found in desktop PCs, the

PCI Express™ clocks are generated from a low

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

LVDS, LVHSTL, SSTL, HCSL

bandwidth, highphase 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 ICS874004

has 3 PLL bandwidth modes: 200KHz, 400KHz, and 800KHz.

200KHz mode will provide maximum jitter attenuation, but with

higher PLL tracking skew and spread spectrum modulation from

the motherboard synthesizer may be attenuated. 400KHz

provides an intermediate bandwidth that can easily track

triangular spread profiles, while providing good jitter attenuation.

800KHz 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. Because some 2.5 Gb serdes

have x20 multipliers while others have than x25 multipliers, the

874004 can be set for 1:1 mode or 5/4 multiplication mode (i.e.

100MHz input/125MHz output) using the F_SEL pin.

• Output frequency range: 98MHz - 160MHz

• Input frequency range: 98MHz - 128MHz

• VCO range: 490MHz - 640MHz

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

• 3.3V operating supply

• 3 bandwidth modes allow the system designer to make jitter

attenuation/tracking skew design trade-offs

• 0°C to 70°C ambient operating temperature

PLL BANDWIDTH

The ICS874004 uses ICS 3^rdGeneration FemtoClock^TMPLL

technology to achieve the lowest possible phase noise. The

device is packaged in a 24 Lead TSSOP package, making it

ideal for use in space constrained applications such as PCI

Express™ add-in cards.
