Box 57013 • Irvine, California 92619-7013 • Phone: 949-450-8700 •Fax: 949-450-8710 1/31/03 10/100BASE-TX Octal- Φ™ Transceiver Figure 1: Functional Block Diagram G EN ER AL DE SC RI PTI O N F EA TU RE S The BCM5238 is an octal 10/100BASE-TX transceiver for Fast Ethernet switches. The device contains eight full- d upl ex 10B ASE-T/1 00BAS E-TX Fa s t Et her net transceivers, each of which performs all of the physical layer interface functions for 10BASE-T Ethernet on Category 3, 4 or 5 unshielded twisted-pair (UTP) cable and 100BASE-TX Fast Ethernet on Category 5 UTP cable. Pseudo-100BASE-FX mode is supported through external fiber-optic tranceivers. The BCM5238 is a highly integrated solution using 0.18- micron technology, comb ining dig i tal a daptive equalizers, ADCs, phase locked loops, line drivers, encoders, decoders and all the required support circuitry into a single monolithic CMOS chip. The BCM5238 complies with the IEEE 802.3 specification, including the auto-negotiation subsections. The BCM5238 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. • 10BASE-T/100BASE-TX IEEE 802.3u compliant • Single-chip octal physical interface—SMII to magnetics • Option—Source Synchronous SMII (SSSMII) • Fully integrated digital adaptive equalizers • 125-MHz clock generator and timing recovery • On-chip multimode transmit waveshaping • Edge-rate control eliminates external filters • HP auto-MDIX • Cable length Indication • Cable noise level Indication • IEEE 802.3u-compliant auto-negotiation • Shared MII management interface up to 25 Mbps • Programmable serial LED pins • Programmable parallel LED pins • Interrupt output capability • Loopback mode for diagnostics • IEEE 1149.1 (JTAG) and NAND-chain ICT support • Low-power dual-supply 2.5V/1.8V CMOS technology • Compatible with 3.3 V I/O • 128 MQFP and 256-pin FBGA package A PP LIC AT I O NS • Fast Ethernet switches MII MII Equalizer Auto-Negotiation LED/INT Clock Bias Registers Mgmt Control Correction /Link Integrity Generator Generator Wander Baseline 8 RXD{1:8} MDC MDIO MODES/CONTROLS TD ± {1:8} RD ± {1:8} REF_CLK Recovery Xmt DAC CRS/Link Detection ADC LED2{1:8} SSSMII_DIS/SLED_CLK Multimode JTAG Test Logic 5 JTAG Digital Adaptive 10BASE-T PCS 100BASE-X PCS Drivers Clock 13 8 INTR/SLED_DO LED1{1:8} 8 8 TXD{1:8} RDAC SSYNC SSSMII_TXC SSSMII_RSYNC Auto MDIX SSSMII_RXC |
