The 100BASE-TX transmitter consists of several functional blocks which convert synchronous 4-bit nibble data, as provided by the MII, to a scrambled MLT-3 125 Mbps serial data stream on the MDI. 4B5B encoding and decoding is detailed in Table 8-7 below.
The transmitter section consists of the following funcitonal blocks:
The bypass option for the functional blocks within the 100BASE-TX transmitter provides flexibility for applications where data conversion is not always required. The DP83822 implements the 100BASE-TX transmit state machine diagram as specified in the IEEE 802.3u Standard, Clause 24.
