PRODUCT OVERVIEW
The 88i8030 family of Serial ATA (SATA) bridge chips, the Þrst offering in the Marvell¨ family of high-speed interface
input/output (I/O) solutions, allows storage OEMs to take advanced data storage systems to the next level of
performance. By converting Parallel ATA to SATA, the Marvell 88i8030 bridge solution allows Hard Disk Drive
(HDD), motherboard and storage subsystem manufacturers to utilize their current Parallel ATA electronics for
faster time-to-market prior to full industry transition to SATA. The 88i8030 devices are designed to interface to
traditional Parallel ATA HDD controllers as well as to host chipsets running up to 150 MBps. Since the bridge allows
parallel connectivity over short trace distances, the 88i8030 product allows for 150 MBps transfer rates with low
noise and high reliability. The devices employ the latest SATA Physical Layer (PHY) technology, starting with the
SATA Working Group-deÞned Generation I speed of 1.5 Gbps, and scalable to 3.0 Gbps to support the future
Generation II, Phase II, SATA speed. The 88i8030Õs PHY leverages four generations
of production-proven
Serializer/Deserializer (SERDES) technology from its industry-leading Alaska¨ Gigabit PHY products. The Marvell
bridge device implements user-selectable SSC for reduced EMI in storage systems. This makes the interface
attractive not only as an inside-the-box technology, but also potentially increases its usefulness for out-of-the-box
interconnects in many consumer electronics applications. The 88i8030 products offer premphasis and amplitude
settings with programmable coefÞcients to help ensure signal integrity over extended trace and cable lengths.
This advanced signaling capability allows for optimal performance in many varieties of storage applications.

APPLICATIONS
The 88i8030 products can be used in a variety of storage system applications. In conjunction with host chipsets or with PCIbased ATA host controllers, the 88i8030 devices enable immediate introduction of SATA-enabled motherboards. When used with
ATA RAID controllers, the 88i8030 devices enable the deployment of SATA RAID. The 88i8030 bridge chip can also be used to
externally convert Parallel ATA HDDs to SATA. In addition, two 88i8030 devices can be used in conjunction with dual-port Parallel
ATA drives for fail-over applications.
