Features - 12/8/4/2-output low-power, push-pull HCSL  patible PCI-Express Gen 1, Gen 2, Gen 3, Gen 4, Gen 5, Gen 6, and SRIS-pliant 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 - I2C support with readback capabilities - Extended temperature: - 40 to 85 °C - 1.5- 1.8 V power supply, with separate VDD and VDD_IO - Small QFN packages - Pb-free, Ro HS-6 pliant Description 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. The Si52202 can source two 100 MHz PCIe clock outputs only. All differential clock outputs are pliant to PCIe  Gen1/2/3/4/5 mon clock and separate reference clock architectures specifications. The Si52212, Si52208, Si52204, and Si52202 feature individual hardware control pins for enabling and  disabling each output, spread spectrum enable/disable for EMI reduction, and frequency select to select 100 MHz, 133 MHz, or 200 MHz differential output  frequencies. These features can also be controlled via I2C. The small footprint and low power consumption make this family of PCIe clock generators ideal for industrial and consumer applications.
