2.5.2.5. Read Test

The receiver is tested using one cycle of preamble and 0x1, 0x0 strobe pattern. PHYLITE_READ_LATENCY must exactly match the internal rddata_en to RcvEn latency of the PHY. The phase shift of RcvEn may need to be adjusted to maximize margin. This test is shown in the following figure.
