Hot-selling and scarce AC101-TF Ultra Low Power 10/100 Ethernet Transceiver QFP spot stock

Product Descriptions

The AC101QF/TF is a highly integrated, 3.3V, low power, 10BASE-T/100BASE-TX/FX, Ethernet transceiver implemented in 0.35 µm CMOS technology. Multiple modes of operation, including normal operation, test mode and power saving mode, are available through either hardware or software control.

Features include MAC interfaces, encoder/decoders (ENDECs), Scrambler/Descrambler, and Auto-Negotiation (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 10 Mbps and 100 Mbps, 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
