PCI Express 1.1 Clock Analysis Tool Overview
PCI Express 1.1 Card Electromechanical (CEM) specification gives the jitter requirements and testing
method for the 100 MHz reference clock. The total jitters for the reference clock are specified at BER=10
-
6
and BER=10
-12
, and are derived from the phase jitter distribution function after a band-pass filter
function is applied. The 1.1 clock tool conducts the 100 MHz reference clock measurement per PCI
Express 1.1 specification requirements and gives total jitter estimations at BER=10
-6
and BER=10
-12
, as
well as indicate whether the results are within the specified values or not (86ps at BER=10
-6
, and 108ps
at BER=10
-12
).
