When the eTSEC is configured for TBI modes, all clocks are supplied from external sources to the relevant
eTSEC interface. In single-clock TBI mode, when a 125-MHz TBI receive clock is supplied on TSECn
pin (no receive clock is used in this mode, whereas for the dual-clock mode this is the PMA1 receive
clock). The 125-MHz transmit clock is applied in all TBI modes.
A summary of the single-clock TBI mode AC specifications for receive appears in
