Residual Spread Spectrum Clock
The Residual Spread Spectrum Clock (rSSC) is generated by modulating the clock
that is used for data generation. It can therefore not be enabled if SJ or SSC is
active.
Residual Spread Spectrum Clock is characterized by:
• Amplitude (peak-to-peak)
• Frequency
There is a dependency between frequency and acceptable amplitude. A graph
indicates whether the chosen setting of frequency and amplitude is acceptable.
