Description
Si53102-A1/A2/A3 is a family of high-performance 1:2 PCIe fan output buffers. This low-additive-jitter clock buffer family is compliant to PCIe Gen 1, Gen 2, Gen 3, and Gen 4 specifications. The ultra-small footprint (1.4x1.6 mm) and industry-leading low power consumption make the Si53102-A1/A2/A3 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/pcielearningcenter.
