Marvell Alaska 88E1548/48P
Quad Port 10/100/1000 Mbps Ethernet Transceivers
With QSGMII or SGMII Interfaces
transceivers
PRODUCT OVERVIEW
Marvell® Alaska® 88E1548/48P Gigabit Ethernet Transceiver is a physical layer device containing four
independent Gigabit Ethernet transceivers. Each transceiver performs all the physical layer functions for
1000BASE-T, 100BASE-TX and 10BASE-T, in full compliance with the 802.3 standards. On the MAC-side
interface, the device supports Quad-Serial Gigabit Media Interface (QSGMII) to Copper or Fiber, Quad-
port SGMII to Copper, or Dual-port SGMII to Fiber.
The 88E1548P version supports the Marvell LinkCrypt® feature, which is based on and implements the
IEEE802.1ae MACsec protocol. This version also supports Precise Timing Protocol (PTP) time stamping,
which is based on IEEE 1588v2 and IEEE 802.1AS, in both two-step and single-step clock operation.
In addition to supporting Energy Efficient Ethernet (EEE) on the new generation of enabled MACs, these
products are also capable of implementing EEE with legacy or non-EEE devices by incorporating EEE
buffering.
The device integrates MDI interface 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.
This device uses advanced mixed-signal processing to perform equalization, echo and crosstalk
cancellation, data recovery and error correction at a Gigabit-per-second data rate. The device achieves
robust performance in noisy environments with very low power dissipation.
The 88E1548/48P integrates an Advanced Virtual Cable Tester® (VCT™) enabling fault detection and
advanced cable performance monitoring.
The Marvell Alaska family of transceiver products provides the ideal solution for rapid development and
deployment of gigabit standalone and switching systems for the Enterprise, embedded, consumer and
Metro/service provider market segments.
