BCM5464R的最新版器件手册。
The BCM5464R transceiver consists of four triplespeed 10/100/1000BASE-T Ethernet transceivers. The
device performs all of the physical layer functions for
1000BASE-T, 100BASE-TX and 10BASE-T Ethernet
on standard Category 5 UTP cable. The BCM5464R is
designed to be fully compliant with the SGMII, RGMII,
and RTBI industry standards.
The BCM5464R is based on Broadcom’s proven digital
signal processor technology, combining digital adaptive
equalizers, ADCs, phase-locked loops, line drivers,
encoders, decoders, echo cancelers, crosstalk
cancelers and all other required support circuitry
integrated into a single monolithic CMOS chip.
Designed for reliable operation over worst-case
Category 5 cable plants, the BCM5464R automatically
negotiates with any transceiver on the opposite end of
the wire to agree on an operating speed. The PHY can
also evaluate the condition of the twisted-pair wiring to
ensure that the wiring can support operation at Gigabit
speeds, and detect and correct most common wiring
problems. The device continually monitors both the
wiring and the opposing transceiver, and alerts the
system if it detects potential problems with reliable
operation.

BCM5461S data sheets
