This chapter provides functional descriptions of the various device features. These features have been
categorized into the following sections:
100BASE-TX Transmit
The 100BASE-TX transmit data path is shown in
following subsections.
100BASE-TX Transmit Data Across the MII/RMII Interface
For MII, the MAC controller drives the transmit data onto the TXD bus and asserts TXEN to indicate
valid data. The data is latched by the transceiver’s MII block on the rising edge of TXCLK. The data
is in the form of 4-bit wide 25MHz data.
