58328-01

The 58328-01 is a specialized physical layer device (PHY) that is used in 10/100 and Gigabit Fast Ethernet network devices. It provides a low latency interface between the Gigabit media access controller (MAC) and the network media, and supports multiple Media Access Control (MAC) protocols. In addition, it supports error control mechanisms, collision detection, and packet buffer configurations.

The 58328-01 PHY is employed in various Ethernet applications including switches, routers, servers, and workstations. It provides a reliable and cost effective solution for the Ethernet physical layer interfaces. The 58328-01 operates at both 10 and 100Mbps data rates, and the interface is configurable to support auto-negotiation or fixed speed operation, depending on the application.

The 58328-01 has 10/100/Gigabit Media Independent Interface (MII), an embedded Digital Terminal Equipment (DTE) compliant link controller, and a selectable I/O voltage range. It supports auto-negotiation for data rate detection, enables MAC-PHY isolation, and provides management capabilities via the MII interface. The 58328-01 implements isolation between the MAC and the PHY, which provides for a high level of immunity to MAC-PHY interaction.

The 58328-01 application field covers a broad range of Ethernet networking applications, as it is compatible with 10BASE-T, 100BASE-TX, and 1000BASE-T technologies. Its features include an integrated link controller for 10/100/Gigabit Ethernet Auto-negotiation, selectable I/O voltage range, and support for 10 or 100 Mbps half-/full-duplex operation. Moreover, the 58328-01 features flow control support, multiple data buffering, and error control mechanisms.

The 58328-01\'s working principle is based on 10/100/Gigabit Ethernet auto-negotiation. When auto-negotiation is enabled, the 58328-01 scans the network for other PHYs and determines the optimal data rate, number of lanes, and I/O voltage. After the optimal parameters are determined, the PHY will attempt to negotiate with the other PHYs and establish a link. Once a link is established, the 58328-01 will then handle all packet transfers and error control.

In addition to its 10/100/Gigabit Ethernet auto-negotiation capabilities, the 58328-01 also supports flow control. Flow control is a technology that enables two network devices to communicate by allowing each device to adjust the rate at which it is sending data. As data packets are sent between the two devices, the 58328-01 monitors the amount of data in transit and adjusts the rate accordingly. This ensures that the connection remains stable and that data is not sent faster than what the receiving device can handle.

The 58328-01 is a versatile PHY that provides an efficient interface between the MAC and the network media, and supports multiple MAC protocols. It is compatible with 10BASE-T, 100BASE-TX, 1000BASE-T, and Auto-negotiation. Furthermore, it features embedded DTE compliant link controller, selectable I/O voltage range, flow control support, multiple data buffering, and error control mechanisms.
