88E1512-A0-NNP2C000 Description

The  Alaska ® 88E1512-A0-NNP2C000 is a physical layer device with one 10/100/1000 Gigabit Ethernet transceiver. The Ethernet physical layer element of the 1000BASE-T, 100BASE-TX, and 10BASE-T specifications is implemented by the transceiver. It's built with conventional digital CMOS technology and includes all of the active circuitry needed to accomplish the physical layer functions for data transmission and reception over standard CAT 5 unshielded twisted pair.

For direct connection to a MAC/Switch port, the device supports the  RGMII  (Reduced pin count GMII) and SGMII.  SFP  modules that enable 1000BASE-X, 100BASE-FX and SGMII can also be connected with the SGMII on the media/line side. With RGMII as the MAC interface, it can also run  Copper /Fiber Auto-media apps. SGMII works at 1.25 Gbps across a single differential pair, decreasing the MAC interface's power consumption and the number of I/Os.

MDI termination resistors are included in the PHY of the device. By minimizing the number of external components, this resistor integration simplifies board layout and lowers board cost. The new  Marvell ® calibrated resistor method will meet or surpass the   IEEE  802.3  return loss specifications in terms of precision.

To create all essential voltages, the device incorporates an integrated switching voltage regulator. A single 3.3V supply can power the device. The device supports LVCMOS I/O standards of 1.8V, 2.5V, and 3.3V.

Synchronous Ethernet (SyncE) and  Precise Timing Protocol  (PTP) Time Stamping are supported by the 88E1512-A0-NNP2C000 device, which is based on IEEE1588 version 2 and IEEE802.1AS. The 88E1512-A0-NNP2C000 device is  IEEE 802.3az-2010 compatible and supports IEEE 802.3az-2010  Energy Efficient Ethernet  (EEE).

The device includes the Marvell Advanced Virtual Cable Tester® (VCTTM) feature, which uses  Time Domain Reflectometry  (TDR) technology to identify potential cable problems remotely, minimizing the need for equipment returns and service calls. The Alaska gadget uses VCT to detect and report potential cabling problems such as pair swaps, pair polarity, and severe pair skew. The gadget will also detect cable openings, shorts, or any impedance mismatch in the cable, correctly indicating the distance to the issue within one meter.

At a data rate of Gigabits per second, the device uses advanced mixed-signal processing to accomplish equalization, echo and crosstalk cancellation, data recovery, and error correction. With very low power dissipation, the gadget achieves stable performance in noisy situations.

Frequently Asked Questions

What does energy efficient Ethernet do?

The Institute of Electrical and Electronics Engineers (IEEE) 802.3az standard, Energy Efficient Ethernet (EEE), decreases the power consumption of physical layer devices (PHYs) during periods of low link utilization. When the link is idle, EEE saves energy by switching a portion of the transmission circuit to low power mode.

Should I enable Energy Efficient Ethernet?

Ethernet is most commonly used in servers, so it is best to keep it on when connected to a server. However, if you are just using one device then energy-efficient ethernet should be disabled to save power.

Does Energy Efficient Ethernet affect performance?

Energy-efficient Ethernet DOES affect performance. Exactly how much will be dependent on the specific Ethernet chipsets involved. Some experts claim up to a drop of 15 %. The biggest effect on performance will be against short-term latency.
