2.0 GENERAL DESCRIPTION
The 100Base-Tx Physical Data Transceiver (PDTR) includes the Physical Data Transmitter (PDT) and the Physical Data
Receiver (PDR). The PDT converts encoded symbols into a serial NRZI data stream. The on-chip PLL generates a bit
rate clock from the TCLKIN or crystal reference. The PDR uses a built-in clock recovery PLL to extract clock information
from the received data stream. The recovered clock is used for serial-to-parallel data conversion.
