PRODUCT OVERVIEW
Alaska 88E1545/88E1543/88E1548
Integrated 10/100/1000 Mbps
Energy Efficient Ethernet Transceiver
Datasheet - Public
The latest generation Alaska® Quad family of single-chip
devices contains four independent Gigabit Ethernet
transceivers on a single monolithic IC. Each transceiver
performs all the physical layer functions for 1000BASE-T
and 100BASE-TX full or half-duplex Ethernet on CAT 5
twisted pair cable, and 10BASE-T full or half-duplex
Ethernet on CAT 3, 4, and 5 cable.
The Alaska 88E1545 device supports the Quad-Serial
Gigabit Media Independent Interface (QSGMII) for direct
connection to a MAC/Switch port. The QSGMII
combines four ports of SGMII running at 1.25 Gbps onto
a single differential-pair of signals operating at 5 Gbps.
QSGMII primarily decreases the number of I/O pins on
the MAC interface compared to the SGMII and lowers
the overall power consumption.
The Alaska 88E1543 device supports SGMII on the MAC
interface in a Copper to SGMII application. In addition,
the SGMII can also be used as media interface for
Fiber/SFP applications. The device can be also
configured to operate in SGMII (System) to Auto-Media
Copper/Fiber mode for mixed media applications.
The Alaska 88E1548 device supports four modes of
operation. Three modes use the QSGMII to support
either copper, SGMII/Fiber or auto media detect to
copper or SGMII/Fiber. The fourth mode supports SGMII
to copper directly. The device supports IEEE 802.3az
Energy Efficient Ethernet (EEE) and is IEEE 802.3az
compliant.
The device integrates MDI termination resistors and
capacitors into the PHY. This resistor integration
simplifies board layout and lowers 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 consumes
400 mW per port in copper applications. This reduces
the overall system cost by eliminating heat-sink and
reducing air-flow requirements.
The device is fully compliant with the IEEE 802.3
standard. The device includes the PMD, PMA, and PCS
sublayers. The device performs PAM5, 8B/10B, 4B/5B,
MLT-3, NRZI, and Manchester encoding/decoding;
digital clock/data recovery; stream cipher
scrambling/descrambling; digital adaptive equalization
for the receiver data path as well as digital filtering for
pulse-shaping for the line transmitter; and
Auto-Negotiation and management functions.
The device supports Auto-MDI/MDIX at all three speeds
to enable easier installation and reduced installation
costs.
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 dissipates very low power
while achieving robust performance in noisy
environments. The device is supported with an
integrated Advanced Virtual Cable Tester® (VCT™)
enabling fault detection and advanced cable
performance monitoring.
