... GENERAL DESCRIPTION The ML6692 implements the complete physical layer of the Fast Ethernet 100BASE-TX standard. The ML6692 interfaces to the controller through the standard-compliant Media Independent Interface (MII). The ML6692 functionality includes auto-negotiation, 4B/5B encoding/ decoding, Stream Cipher scrambling/descrambling, 125MHz clock recovery/generation, receive adaptive equalization, baseline wander correction, and MLT-3/ 10BASE-T transmitter ...

The ML6692 presents a linear copy of the input at 10BTTXINP/N to the TPOUTP/N outputs when the ML6692 functions in 10BASE-T mode. Signals presented to these pins must be centered at V amplitude of ± ...
