874002規(guī)格書詳情
GENERAL DESCRIPTION
The 874002 is a high performance Differential-to-LVDS 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
874002 has 3 PLL bandwidth modes: 200kHz, 400kHz,
and 800kHz. The 200kHz mode will provide maximum jitter
attenuation, but with higher PLL tracking skew and spread
spectrum modulation from the motherboard synthesizer may
be attenuated. The 400kHz provides an intermediate bandwidth that can easily track triangular spread profi les, while providing
good jitter attenuation. The 800kHz bandwidth provides the best
tracking skew and will pass most spread profi les, but the jitter
attenuation will not be as good as the lower bandwidth modes.
Because some 2.5Gb serdes have x20 multipliers while others
have than x25 multipliers, the 874002 can be set for 1:1 mode or
5/4 multiplication mode (i.e. 100MHz input/125MHz output) using
the F_SEL pin.
The 874002 uses IDT’s 3rd Generation FemtoClock TM
PLL technology to achieve the lowest possible phase noise.
The device is packaged in a 20 Lead TSSOP package, making it
ideal for use in space constrained applications such as PCI Express
add-in cards.
