Si53154-EVB Si53154 EVALUATION BOARD USERS GUIDE Description EVB Features The Si53154 is a four port PCIe clock buffer compliant This document is intended to be used in conjunction to the PCIe Gen1, Gen2 and Gen3 standards. The with the Si53154 device and data sheet for the following Si53154 is a 24-pin QFN device that operates on a tests: 3.3 V power supply and can be controlled using SMBus PCIe Gen1, Gen2, Gen3 compliancy signals along with hardware control input pins. The Power consumption test device is spread aware and accepts a frequency spread Jitter performance differential clock frequency range from 100 to 210 MHz. 2 The connections are described in this document.
