GENERAL DESCRIPTION
The 9DB202-01 is a high performance 1-to-1 Differential-to HCSL
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
attenuating device may be necessary in order to reduce high
frequency random and deterministic jitter com-ponents from the
PLL synthesizer and from the system board.
