BCM5461S英文资料下载

　　The BCM5461S consists of a triple-speed 1000BASE-T/ 100BASE-TX/FX/10BASE-T Gigabit Ethernet transceiver integrated into a single monolithic CMOS chip. The device performs all physical-layer functions for 1000BASE-T， 100BASE-TX/FX， and 10BASE-T Ethernet on standard Category 5 UTP cable. 10BASE-T can also run on standard Category 3， 4， and 5 UTP. The BCM5461S also has a serial interface for connection to serial MAC interface and fiber modules. The BCM5461S is a highly integrated solution combining digital adaptive equalizers， ADCs， phase-locked loops， line drivers， encoders， decoders， echo cancellers， crosstalk cancellers， and all required support circuitry. Based on Broadcom’s proven digital signal processor technology， the BCM5461S is designed to be fully compliant with RGMII， GMII， MII， TBI， and RTBI， allowing compatibility with industry-standard Ethernet MACs and switch controllers. The BCM5461S includes a shared SerDes/SGMII interface that can be connected to an SGMII MAC or a SerDes/fiber transceiver. The BCM5461S supports 100BASE-FX optical modules through the twisted pair. GBIC mode provides SerDes-to-copper translation capability.
