9.13.1. Phase 0

Phase 0 includes the following steps:
  1. Upstream component enters Phase 0 of equalization during Recovery.Rcvrconfig by sending EQ TS2 training sets with starting presets for the downstream component. EQ TS2 training sets may be sent at 2.5 GT/s or 5 GT/s.
  2. The downstream component enters Phase 0 of equalization after exiting Recovery.Speed at 8 GT/s. It receives the starting presets from the training sequences and applies them to its transmitter. At this time, upstream component has entered Phase 1 and is operating at 8 GT/s.
  3. To move to Phase 1, the receiver must have a BER < 10-4 and should be able to decode enough consecutive training sequences.
  4. The downstream component must detect training sets with Equalization Control (EC) bits set to 2’b01 in order to move to EQ Phase 1.
