描述
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 components from the PLL synthesizer and from the system board.
特性
- One 0.7V current mode differential HCSL output pair
- One differential clock input
- CLK and nCLK supports the following input types: LVPECL, LVDS, LVHSTL, SSTL, HCSL
- Maximum output frequency: 140MHz
- Input frequency range: 90MHz - 140MHz
- VCO range: 450MHz - 700MHz
- Cycle-to-cycle jitter: 30ps (maximum)
- RMS phase jitter @ 100MHz, (1.5MHz - 22MHz): 2.31ps (typical)
- 3.3V operating supply
- 0°C to 70°C ambient operating temperature
- Available in lead-free RoHS compliant package
- Industrial temperature information available upon request

PCIe Clocking Architectures (Common and Separate)
This is the first video in our PCIe series. In this video, we define PCIe architectures, focusing on common and separate clock architectures. Watch the rest of the video series below where Ron will cover the impact of different timing architectures.
