UG337: Si53208-EVB User’s Guide
8-Output PCI-Express Gen1/2/3/4 and SRIS Clock Buffer Evalua-
tion Board
This document describes operation of the Silicon Laboratories Si53208-EVB evaluation
board. It’s designed to evaluate the Si53208, 8-output PCI-Express Gen1/2/3/4 which
is an SRIS Clock Buffer. Selector switches make it easy to select the voltage for both
core and IO supplies. Jumpers allow for easy static configuration of the control inputs
as well as provide a port for external test equipment access. Similarly, each regulated
supply can be bypassed and driven externally for either precise voltage control or for
measuring PSRR performance. Convenient probe pads and isolation resistors permit
on-board single-ended or differential measurements. Finally, the PCB layout optimizes
signal integrity and skew which rounds out the capabilities of this EVB.
