AC101QF/TF

Ultra Low Power 10/100 Ethernet Transceiver

GENERAL DESCRIPTION

The AC101QF/TF is a highly integrated, 3.3V, low

power,

transceiver

technology. Multiple modes of operation, including

normal operation, test mode and power saving mode,

are available through either hardware or software

control.

Features

Scrambler/Descrambler,

(ANeg) with support for parallel detection. The

transmitter includes a dual-speed clock synthesizer

that only needs one external clock source (crystal or

clock oscillator). The chip has built-in wave shaping

driver circuit for both 10Mbps and 100Mbps,

eliminating the need for an external hybrid filter.

The receiver has an adaptive equalizer / DC

restoration circuit for accurate clock and data

recovery for the 100Base-TX signal. It also provides

an on-chip low pass filer / Squelch circuit for the

10Base-T signal.

MAC interfaces to support 10/100 MII, 100M only

Symbol Mode, 10M only Symbol Mode and 10M

only 7 wire interface are included.

The AC101TF and the AC101QF are the same

product in different packages.
