High Definition PCI Express Single Chip

Product Overview

M1697 is ULi's latest PCI Express™ single chip designed to empower high-performance PCI Express™-based PC systems to complement the wide range of AMD64 processors including : Socket M2, Socket 940, Socket 939 and Socket 754 processors.

Built upon the innovative architecture of its predecessor M1689, ULi M1697 delivers the lowest latency to achieve maximum system performance while providing manufacturers unmatched design-flexibility and worthily inexpensive manufacturing cost.

M1697 features highly scalable PCI Express™ interfaces at 1 x16 or 2 x8 (4GB/sec peak bandwidth per direction) for graphics and 3 x1 /or 1 x4 for high-speed I/O devices to fulfill various market requirements. The employment of the HyperTransport™ technology between M1697 and the connecting processor delivers the highest continuous throughput of up to 8 GB/sec that ensures sufficient bandwidth to boost overall system performance.

On board M1697 are 3 key powerful features. The High Definition (HD) Audio technology delivers breathtaking 7.1-channel surround audio experience. The AHCI-based Serial ATA host controller module is embedded with NCQ (Native Command Queuing) capability and supports up to 4 ports with each running at up to 3Gb/s. The added implementation of the RAID 0, 1, 0+1, 5, JBOD technologies help optimize storage performance and improve disk efficiency.
