Product Overview

The Alaska® 88E1510/88E1518/88E1512/88E1514 device is a physical layer device containing a single 10/100/1000 Gigabit Ethernet transceiver. The transceiver implements the Ethernet physical layer portion of the 1000BASE-T, 100BASE-TX, and 10BASE-T standards. It is manufactured using standard digital CMOS process and contains all the active circuitry required to implement the physical layer functions to transmit and receive data on standard CAT 5 unshielded twisted pair.

The device supports the RGMII (Reduced pin count GMII) and SGMII for direct connection to a MAC/Switch port. The SGMII can also be used on media/line side to connect to SFP modules that support 1000BASE-X, 100BASE-FX and SGMII. It also supports Copper/Fiber Auto-media applications with RGMII as the MAC interface. SGMII operates at 1.25 Gbps over a single differential pair thus reducing power and number of I/Os used on the MAC interface.

The device integrates MDI termination resistors into the PHY. This resistor integration simplifies board layout and reduces board cost by reducing the number of external components. The new Marvell® calibrated resistor scheme will achieve and exceed the accuracy requirements of the IEEE 802.3 return loss specifications.

The device has an integrated switching voltage regulator to generate all required voltages. The device can run off a single 3.3V supply. The device supports 1.8V, 2.5V, and 3.3V LVCMOS I/O Standards.

The 88E1510/88E1518/88E1512/88E1514 device supports Synchronous Ethernet (SyncE) and Precise Timing Protocol (PTP) Time Stamping, which is based on IEEE1588 version 2 and IEEE802.1AS.

The 88E1510/88E1518/88E1512/88E1514 device supports IEEE 802.3az-2010 Energy Efficient Ethernet (EEE) and is IEEE 802.3az-2010 compliant.

The device incorporates the Marvell Advanced Virtual Cable Tester® (VCT™) feature, which uses Time Domain Reflectometry (TDR) technology for the remote identification of potential cable malfunctions, thus reducing equipment returns and service calls. Using VCT, the Alaska device detects and reports potential cabling issues such as pair swaps, pair polarity and excessive pair skew. The device will also detect cable opens, shorts or any impedance mismatch in the cable and reporting accurately within one meter the distance to the fault.

The device uses advanced mixed-signal processing to perform equalization, echo and crosstalk cancellation, data recovery, and error correction at a Gigabits per second data rate. The device achieves robust performance in noisy environments with very low power dissipation.

Ethernet is a communication standard that was developed in the early ’80s to network computers and other devices in a local environment such as a home or a building.

This local environment is defined as a LAN (Local Area Network) and it connects multiple devices so that they can create, store and share information with others in the location.

Ethernet is a wired system that started with using coaxial cable and has successfully progressed to now using twisted pair copper wiring and fiber optic wiring.

Let’s break for a trivia question. Who invented twisted pair wiring?

Alexander Graham Bell invented twisted pair wiring in 1881.

In 1983, Ethernet was standardized into the standard IEEE 802.3 by the Institute of Electrical and Electronic Engineers (IEEE).

This standard defined the physical layer and the MAC (media access control) portion of the data link layer of wired Ethernet.

These two layers are defined as the first two layers in the OSI (Open Systems Interconnection) model

The “physical” layer consists of the following components: Cabling and Devices.

First, let’s take a look at Ethernet Cabling;

As stated previously, Ethernet cables come as coaxial cable, which is not very common except in older installations, twisted pair, and fiber optic.

The most common cable is twisted pair cables, with the latest being Category 6 with speeds up to 1 Gbps and Cat6a and Cat 7 with speeds up to 10 Gbps.

Category 5 and 5e cables are both still used in many existing applications but handle the lower speeds between 10 Mbps to 100 Mbps but are more susceptible to noise.

The Ethernet twisted pair utilizes RJ-45 eight-pin connectors at either end of the cable that is pinned for transmitting and receiving data in either half or full-duplex mode.

88E1518-A0-NNB2C000 FAQ

What is an Ethernet Transceiver?

An Ethernet transceiver is a hardware device designed to connect computers or electronic devices within a network, allowing them to transmit and receive messages. A transceiver consists of a transmitter and a receiver, hence the name. An Ethernet transceiver is also known as a media access unit (MAU).

What is the purpose of a transceiver?

The transceiver is an important part of a fiber optics network and is used to convert electrical signals to optical (light) signals and optical signals to electrical signals. It can be plugged into or embedded into another device within a data network that can send and receive a signal.

What are the types of transceiver?

There are many types of transceivers: RF transceivers, fiber-optic transceivers, Ethernet transceivers, wireless (WAP) transceivers, and more. Though each of these media types is different, the function of the transceiver remains the same.

What are wireless transceivers?

A wireless transceiver is a central component of wireless communication systems. The quality of the wireless transceiver determines the reliability and efficiency of information delivery in the wireless system.

Is a transceiver a switch?

Optical fiber transceiver is a relatively simple network hardware equipment, the interface is less than the switch, so its wiring and connection is relatively simple. They can be used alone or mounted in a rack.
