Si52202
Overview
The Si52212, Si52208, Si52204, and Si52202 are a high performance and low power PCI Express clock generator family for 1.5 V to 1.8 V PCIe Gen 1/2/3/4/5/6 and SRIS applications. The Si52212, Si52208, and Si52204 can source twelve, eight, and four 100 MHz PCIe differential clock outputs, respectively, plus one 25 MHz LVCMOS reference clock output.
- 12/8/4/2-output low-power, push-pull HCSL compatible PCI-Express Gen 1, Gen 2, Gen 3, Gen 4, Gen 5, Gen 6, and SRIS-compliant outputs
- Low jitter: 0.085 ps rms, Gen 6
- Individual hardware control pins and I2C controls for Output Enable, Spread Spectrum Enable and Frequency Select
- Triangular spread spectrum for EMI reduction, down spread 0.25% or 0.5%
- Internal 100 Ω or 85 Ω line matching
- Adjustable output slew rate
- Power down (PWRDNb) function supports Wake-on LAN (except Si52202)
- One non-spread, LVMCOS reference clock output (except Si52202)
- Frequency Select to select 133 MHz or 200 MHz (except Si52202)
- 25 MHz crystal input or clock input
