Description

The Si53108-EVB can be used to evaluate the Si53108-
A01AGM, an 8-output PCIe Gen1/2/3 buffer that can
operate in either fanout or zero delay mode.

Features

10-inch traces to evaluate signal integrity

The signal traces of the input and outputs have a 
single-ended impedance of 50 ohms, and differential 
impedance of 100 ohms.

The series resistance on the outputs are set to 
match to this impedance design.

DC pin controls per data sheet specification.

Ability to measure input to output propagation delay.

Ability to measure PCIe clock jitter.

Ability to program features of Si53108-A01AGM via 

I

2

C interface.
