    GMII Receive AC Timing Specifications
    Table 21 provides the GMII receive AC timing specifications.
    Figure 8 provides the AC test load for TSEC.
    Figure 8. TSEC AC Test Load
    Figure 9 shows the GMII receive AC timing diagram.

    Note:
    1. The symbols used for timing specifications herein follow the pattern of t(first two letters of functional block)(signal)(state)
    (reference)(state) for inputs and t(first two letters of functional block)(reference)(state)(signal)(state) for outputs. For example, tGRDVKH
    symbolizes GMII receive timing (GR) with respect to the time data input signals (D) reaching the valid state (V) relative to
    the tRX clock reference (K) going to the high state (H) or setup time. Also, tGRDXKL symbolizes GMII receive timing (GR)
    with respect to the time data input signals (D) went invalid (X) relative to the tGRX clock reference (K) going to the low (L)
    state or hold time. Note that, in general, the clock reference symbol representation is based on three letters representing
    the clock of a particular functional. For example, the subscript of tGRX represents the GMII (G) receive (RX) clock. For rise
    and fall times, the latter convention is used with the appropriate letter: R (rise) or F (fall).
    2. Signal timings are measured at 0.7 V and 1.9 V voltage levels.
    3. Guaranteed by design.
