The AC101L is a single-channel, low-power,

1 0 /10 0 BASE-TX/FX tra n s c ei v e r. T he AC10 1L

transceiver has an integrated voltage regulator to allow

operation from a single 3.3V or 2.5V supply source. The

device contains a full-duplex 10BASE-T/100BASE-TX/

100BASE-FX Fast Ethernet transceiver, which performs

all of the physical layer interface functions.

The AC101L is a highly integrated solution combining an

encoder/decoder , link mo nitor, auto-n egotiation

selection, parallel detection, adaptive equalization, clock/

data recovery, baseline wander correction, multimode

transmitter, scrambler/descrambler, far-end fault (FEF),

and auto-MDI/MDIX circuitry.
