PRODUCT OVERVIEW
The 88E3082/88E3083 devices are third generation Marvell
transceivers. The devices offer the industrys lowest power consumption at only 150mW per port resulting
in higher port density, lower cost FE switches. Additionally, the 88E3082/88E3083 devices integrate the industrys
most advanced feature set, such as Virtual Cable Tester
a
technology for remote cable diagnostics and the
support for very low power modes.
¨
DSP-based 8-port 10/100BASE-T Fast Ethernet (FE)
The 88E3082/88E3083 devices contain all of the active circuitry to convert data streams to and from eight
Media Access Controllers (MACs) and the physical media. The 88E3082 device incorporates IEEE 802.3u Auto-
Negotiation in support of both 100BASE-TX and 10BASE-T networks over twisted-pair cable in full-duplex or
half-duplex mode.
