Box 57013 • Irvine, CA 92619-7013 • Phone: 949-450-8700 • Fax: 949-450-8710 9/9/02 Ultra Low Power 10/100 Quad SMII/RMII Ethernet Transceiver Figure 1: Functional Block Diagram G EN ER AL DE SC RI PTI O N F EA TU RE S The AC104Z is a highly integrated, 3.3V, low-power, four- port, 10BASE-T/100BASE-TX, 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, 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. The chip has built-in, wave shaping driver circuit for both 10 Mbps and 100 Mbps, thereby eliminating the need for an external hybrid filter. The receiver has an adaptive equalizer/DC restoration circuit for accurate clock/data recovery for the 100BASE-TX signal. The receiver also provides an on-chip low pass filer/Squelch circuit for the 10BASE-T signal. MAC interfaces support four ports of 10/100 RMII and SMII. Media interfaces support four ports of 10/100TX/FX. • 4 ports with RMII MAC interface • 4 ports with 10/100 TX media interface • Full-duplex or half-duplex • FEFI on 100FX • Very small package • 128PQFP • Very low power – TYP < 280 mW per port • Cable detect mode – TYP < 40 mW per port • Power Down mode – TYP < 3.3 mW per port • Selectable TX drivers for 1:1 or 1.25:1 transformers for additional power reduction • 3.3V.35 micron CMOS • (S/R) MII SV tolerant • Fully compliant with • IEEE 802.3 / 802.3u • SMII/RMII • UNH test labs • Baseline wander compensation • Multi-function LED outputs • Cable length indicator • Reverse polarity detection and correction with register bit indication – automatic or forced • 8 programmable interrupts Port 0 Port 1 Port 2 Mux MII Serial Management Interface and Registers PLL Clk Gen.
