Reference Clock (REF_CLK)
REF_CLK is a continuous 50MHz clock that provides the timing reference for TX_EN, TXD[1:0], CRS_DV, RXD[1:0], and
RX_ER.
The KSZ8041NL inputs the 50MHz REF_CLK from the MAC or system board.
The KSZ8041RNL generates the 50MHz RMII REF_CLK and outputs it to the MAC.
Transmit Enable (TX_EN)
TX_EN indicates that the MAC is presenting di-bits on TXD[1:0] for transmission. It is asserted synchronously with the first
nibble of the preamble and remains asserted while all di-bits to be transmitted are presented on the RMII, and is negated
prior to the first REF_CLK following the final di-bit of a frame.
TX_EN transitions synchronously with respect to REF_CLK.
Transmit Data [1:0] (TXD[1:0])
TXD[1:0] transitions synchronously with respect to REF_CLK. When TX_EN is asserted, TXD[1:0] are accepted for
transmission by the PHY. TXD[1:0] is ”00” to indicate idle when TX_EN is de-asserted. Values other than “00” on TXD[1:0]
while TX_EN is de-asserted are ignored by the PHY.
