Hot-selling and scarce 88E3082-C1-BAR1I000 Transceiver IC BGA spot stock

Product Descriptions

The Marvell Alaska 88E3082 and 88E3083 are third-generation  Marvell DSP-based 8-port 10/100BASE-T Fast Ethernet (FE)  transceivers. They offer the industry’s lowest power  consumption at only 150mW per port, resulting in higher port  density, lower cost FE switches. Additionally, the 88E3082 and  88E3083 integrate the industry’s most advanced FE transceiver  feature set, such as Marvell’s Virtual Cable Tester® (VCT™)  technology for remote cable diagnostics and support for very  low power modes.

The Alaska 88E3082 and 88E3083 contain all of the active circuitry to convert data streams to and from eight Media Access Controllers (MACs) and to and from the physical media. In addition, both devices incorporate IEEE 802.3u AutoNegotiation in support of both 100BASE-TX and 10BASE-T networks over twisted-pair cable in full-duplex or half-duplex mode.

To reduce the number of input/output (I/O) pins between the  MAC and the Physical Layer (PHY), the 88E3082 supports the  Reduced Media Independent Interface (RMII), the Serial Media  Independent Interface (SMII), and the source-synchronous  option of SMII (SSSMII). The SSSMII interface extends the  allowed PCB trace distance between the PHY and the MAC,  thereby facilitating more robust, higher port density FE switch  designs. The 88E3083 supports the SMII and SSSMII interfaces.

The 88E3082 also features a mode of operation supporting  IEEE-compliant 100BASE-FX fiber-optic networks. The device  includes a PECL interface that is selectable on a per-port basis  for 100BASE-FX applications. The 88E3083 supports 100BASEFX fiber on a single port.
