REFCLK phase jitter specifications
Web-exclusive material accompanying our August 2006 feature article, "PCI Express: Beyond minimum compliance."
Mike Li and Rich Vignes, Wavecrest -- Test & Measurement World, 8/1/2006
The phase jitter of the reference clock is to be measured using the following jitter transfer function:
The maximum allowed phase jitter when applied to the fixed filter characteristic is given in the following table:
|
BER |
Maximum peak-to-peak phase jitter values (ps) |
|
10–6 |
86 |
|
10–12 |
108 |
