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.
