Description

The Si53112-EVB can be used to evaluate the Si53112-
A01AGM, a 12-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 Si53112-A01AGM 

via I

2

C interface.
