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 TBICON[CLKSEL] = 1, a 125-MHz TBI receive clock
is supplied on the TSECn_RX_CLK pin (no receive clock is used on TSECn_TX_CLK in this mode,
whereas for the dual-clock mode this is the PMA1 receive clock). The 125-MHz transmit clock is applied
on the TSEC_GTX_CLK125 pin in all TBI modes.

PMA_RX_CLK[0:1] duty cycle
RCG[9:0] setup time to rising PMA_RX_CLK
PMA_RX_CLK to RCG[9:0] hold time
PMA_RX_CLK[0:1] clock rise time (20%-80%)
PMA_RX_CLK[0:1] clock fall time (80%-20%)
Note:
1. The symbols used for timing specifications follow the pattern of t
inputs and t
timing (TR) with respect to the time data input signals (D) reach the valid state (V) relative to the t
going to the high (H) state or setup time. Also, t
signals (D) went invalid (X) relative to the t
reference symbol representation is based on three letters representing the clock of a particular functional. For example, the
subscript of t
appropriate letter: R (rise) or F (fall). For symbols representing skews, the subscript is skew (SK) followed by the clock that
is being skewed (TRX).
