When you power VCC and VCCP at nominal voltage of 0.90 V.
When you power VCC and VCCP at lower voltage of 0.83 V.
You can estimate the achievable maximum data rate for non-DPA mode by performing link timing closure analysis. You must consider the board
skew margin, transmitter delay margin, and receiver sampling margin to determine the maximum data rate supported.
When you power VCC and VCCP at nominal voltage of 0.90 V.
