8.2.29 Single Clock MII (SCMII) Receive Timing
Note: Output delays assume a 25pF load.
Note: CRS is asserted and deasserted asynchronously relative to the reference clock.
Note: CRS ON delay is measured from the first bit of the JK symbol on the PMD Receive Pair to assertion of CRS_DV.
Note: CRS_OFF delay is measured from the first bit of the TR symbol on the PMD Receive Pair to deassertion of
CRS_DV.
Note: Receive Latency is measured from the first bit of the symbol pair on the PMD Receive Pair. Typical values are with
the Elasticity Buffer set to the default value (01).
