Si52144 EVALUATION BOARD USER’S GUIDE
Description
EVB Features
The Si52144 is a four port PCIe clock generator
compliant with the PCIe Gen1, Gen2 and Gen3
standards. The Si52144 is a 24-pin QFN device that
operates on a 3.3 V power supply and can be controlled
using SMBus signals along with hardware control input
pins. The differential outputs support spread spectrum
and can be controlled through SSON input pin. The
Si52144 needs a crystal or clock input of 25 MHz. The
connections are described in this document.
This document is intended to be used in conjunction
with the Si52144 device and data sheet for the following
tests:
 PCIe Gen1, Gen2, Gen3 compliancy
 Power consumption test
 Jitter performance
 Testing out I²C code for signal tuning
 In-system validation where SMA connectors are
present
