The device integrates all of the circuitry required for 100/1000BASE-T Ethernet on-chip, and provides a glueless interface to an external 10BASE-T transceiver for 10/100/1000BASE-T support. The chip is based on a highly advanced DSP architecture combining digital adaptive equalizers, encoders, decoders, echo cancellers, crosstalk cancellers, ADCs, phase lock loop, line drivers, and all required support circuitry. The BCM5400 easily interfaces to Ethernet MACs and repeater controllers that are compliant with the IEEE 802.3 GMII (Gigabit Media Independent Interface), or TBI (10-bit interface for SERDES). A 125-MHz clock with low jitter is generated internally to eliminate external clocking circuitry for the GMII or TBI interfaces. The BCM5400 makes Gigabit Ethernet network equipment easier to install by automatically detecting and correcting the most common wiring problems. These include the ability to automatically configure MDI crossover, correct pair swaps, pair skew, and pair polarity problems. Plug and Play operation is achieved through support of IEEE auto-negotiation for 10/100/1000 Mbps in full- and half-duplex modes. In 1000BASE-T mode, the BCM5400 transmits and receives data on CAT 5 UTP using a five-level pulse amplitude modulated (PAM5) data stream. The chip transmits and receives data simultaneously on all four pairs of the UTP cable. In 100BASETX mode, the BCM5400 transmits and receives data on separate pairs using a three-level MLT3 encoded serial data stream in accordance with the IEEE 802.3u standard. The BCM5400 integrates a complete transceiver from GMII, or TBI, to magnetics.
