100M Transmit Driver
The MLT3 data is then passed to the analog transmitter, which drives the differential MLT-3 signal, on
outputs TXP and TXN, to the twisted pair media across a 1:1 ratio isolation transformer. The 10BASE-
T and 100BASE-TX signals pass through the same transformer so that common “magnetics” can be
used for both. The transmitter drives into the 100 Ω impedance of the CAT-5 cable. Cable termination
and impedance matching require external components.
100M Phase Lock Loop (PLL)
The 100M PLL locks onto reference clock and generates the 125 MHz clock used to drive the 125 MHz
logic and the 100BASE-TX transmitter.
