SMII_INPUTS
SMII_RXCLK
Timing was designed for a system load between 5pF and 15pF
These values satisfy t the MII specification requirement of 0 ns to 25 ns clock to output delay.
Timing was designed for a system load between 5 pF and 15 pF.
eth_tx_clk
eth_tx_en
Clock to output delay for ETH_TXDATA and
ETH_TXEN.
ETH_TXDATA and ETH_TXEN hold time after
ETH_TXCLK.
SMII_RXD and SMII_RXSYNC setup time prior to
rising edge of SMII_RXCLK
SMII_RXD and SMII_RXSYNC hold time after the
rising edge of SMII_CLK
