Description  
The Si52146 is a high-performance, PCIe clock generator that can source six  
PCIe clocks from a 25 MHz crystal or clock input. The clock outputs are  
compliant to PCIe Gen 1, Gen 2, Gen 3, Gen 3 SRNS and Gen 4 common  
clock specifications. The device has six output enable control pins for  
enabling and disabling differential outputs. A spread spectrum control pin for  
EMI reduction is also available. The small footprint and low power  
consumption makes the Si52146 the ideal clock solution for consumer and  
embedded applications. Measuring PCIe clock jitter is quick and easy with the  
Silicon Labs PCIe Clock Jitter Tool. Download it for free at www.silabs.com/
