The BCM5222 operates using a 1.8V and 3.3V supply. The devices contain two full-duplex 10BASE-T/100BASE-TX Fast Ethernet transceivers, which perform all of the physical layer interface functions for 10BASE-T Ethernet on CAT 3, 4, and 5 unshielded twisted pair (UTP) cable and 100BASE-TX Fast Ethernet on CAT 5 UTP cable. The BCM5222 is a highly integrated solution combining a digital adaptive equalizer, ADC, phase lock loop, line driver, encoder, decoder and all the required support circuitry into a single monolithic CMOS chip. It complies fully with the IEEE 802.3u specification, including the Media Independent Interface (MII) and Auto-Negotiation subsections. The effective use of digital technology in the BCM5222 design results in robust performance over a broad range of operating scenarios. Problems inherent to mixed- signal implementations, such as analog offset and on- chip noise, are eliminated by employing field proven digital adaptive equalization and digital clock recovery techniques. • Dual Port 10/100BASE-TX IEEE 802.3u Fast Ethernet Transceiver • Power Consumption: <180 mW/port • Unique Energy Detection Circuit to Enable Intelligent Power Management • HP Auto-MDIX • Cable Length Indication • Cable Noise Level Indication • Cable length greater than 140 meters • Well Under 10 PPM defect ratio quality • Industrial Temperature Range (-40 to 85C) • MII/7-wire serial interface • IEEE 1149.1 (JTAG) Scan Chain Support • MII Management Via Serial Port • 100-pin PQFP and 100-pin fpBGA packages APPLICATIONS • IP Phones • Backplane Bus Communication • Embedded Telecom • Print Servers MII MII Equalizer Auto-Negotiation LED Clock Bias Registers Mgmt Control Correction /Link Integrity Generator Generator Wander Baseline TXD[1:2] TXEN[1:2] TXER[1:2] TXC[1:2] COL[1:2] RXC[1:2] CRS[1:2] RXDV[1:2] RXER[1:2] RXD[1:2] LNKLED#[1:2] MDC MDIO MODES TD ±[1:2] RD ±[1:2] XTALO Recovery Xmt DAC ADC SPDLED#[1:2] Multimode Digital Adaptive 10BASE-T PCS 100BASE-TX PCS Drivers Clock XTALI RDAC ACTLED#[1:2] Detection CRS/Link 4 4 JTAG Test Logic JTAG 5 Auto MDIX FDXLED#[1:2] |
