Preliminary Data Sheet
1. The reference clock frequency specification does not include 5700ppm frequency offset specification.
2. The data rate can be modulated from + 0% to − 0.5% of the nominal data rate frequency, at a modulation rate in the range not exceeding
3. Only 100MHz or 120MHz is supported.
30kHz–33kHz. The ±350ppm requirement remains which requires the two communcicating ports to be modulated so that they never
exceed a total of 700ppm difference. For most implementations, this requires that both ports have the same bit rate clock source when
the data is modulated with an SSC.
