Marvell Prestera™-DX Switch Family Drives the Transition to Gigabit Ethernet in Small, Medium Businesses

Prestera-DX Family First to Enable Switch Manufacturers to Achieve Sub-$75 Retail Per Gigabit Ethernet Port

Taipei, Taiwan and Sunnyvale, California (June 17, 2002) –

Marvell® (NASDAQ: MRVL), a technology leader in the development of extreme broadband communications solutions, today introduced the Prestera™-DX high-density Gigabit Ethernet switch processor family for small and medium business desktop switches, further accelerating the market transition from Fast Ethernet to Gigabit Ethernet. Addressing this market's need for unmanaged and economical solutions, the Prestera-DX Gigabit Ethernet switch processors provide an easy-to-use networking architecture that enables system vendors to design very affordable, plug-and-play, high-density Gigabit Ethernet unmanaged and fully-managed switches.

While still incorporating many of the quality and performance features of the "enterprise" Prestera-EX and "metropolitan" Prestera-MX processors, the Prestera-DX family focuses on the requirements of the desktop environment. Advanced desktop features, such as those required for voice over Internet Protocol (VoIP), include support for Layer 3 IP prioritization, four queues for voice/video/data/management and sub 0.01 ms latency. Because these solutions are typically unmanaged or lightly managed switches, the Prestera-DX family rapidly reduces development time by providing standard default configurations without the need for a CPU; where management is desired, this can be accomplished using a Serial ROM or ultra-low cost CPU.

"Although desktop storage capacities have increased 100x since the introduction of Fast Ethernet, the bandwidth to the desktop has remained unchanged, creating a bottleneck within the network for events such as backups and remote storage. The Prestera-DX architecture removes this bottleneck by enabling the rapid migration to Gigabit Ethernet within small and medium businesses, complementing the increased adoption of Gigabit Ethernet already seen within larger enterprise networks," said Gary Smerdon, Marvell's Vice President of Marketing for the Communications Business Group.

"With three generations of Gigabit switches in volume production and our industry-leading Alaska® Quad and Octal PHY products, Marvell continues the market-leading drive of 'Gigabit Ethernet everywhere'," said Michael McDonald, Marvell's Director of Marketing for the Switching Products Group. "With the introduction of our Prestera-DX family, Marvell has now opened up a new class of Gigabit Ethernet products in the mainstream, very high-volume desktop switch arena."

Marvell Prestera-DX Family: Market-Leading Features at Economical Prices

The Marvell Prestera-DX120 is a 12-port Gigabit Ethernet solution supporting a high-speed 16 Gbps uplink bus for connection to other devices for configurations such as a full-wire-speed 24-port Gigabit Ethernet system. The Prestera-DX120 device supports the ability to switch traffic to over 4000 addresses, double that of many desktop switches on the market today. In addition, this device supports up to 32 virtual LANs (VLANs), providing a valuable mechanism for enhanced security, simplified management and more efficient utilization of network resources. The Prestera-DX devices combined with the Alaska Gigabit Ethernet PHY products provide a complete system solution for Gigabit Ethernet switches.

Some of the other Prestera-DX features that make it ideal for desktop and small business switches include the following:

  • Plug-and-play configuration for easy system design and rapid time-to-market.
  • Sub 5 Watt power consumption enables the development of very small Gigabit Ethernet switches that do not require a fan.
  • Broadcast and multicast rate limiting features that limit flooding of traffic, important for both security (Broadcast Storm protection) and network bandwidth management.
  • Easily programmable and software compatible with the Prestera-EX and Prestera-MX families.


For large quantities, a 24-port Gigabit Ethernet switch can be designed using two Prestera-DX120 (98DX120) devices and six Alaska Quad 88E1041 Gigabit Ethernet transceivers for a total of $430, or less than $18 per Gigabit Ethernet port. The Alaska Quad 88E1041 transceiver is shipping in volume production; general sampling for the Prestera-DX products are expected in August.
