Product Summary
The JMH330 is a Serial ATA Bridge Chip. It includes the Serial ATA PHY, Link, Transport, and parallel ATA (application layer) controller. The main applications of the JMH330 are for serial ATA storage devices connecting to traditional IDE south bridge. For traditional IDE host, the bridge supports master only. The Serial ATA physical, link, and transport layer are compliance to Serial ATA Generation 1, which supports a 1.5Gbps data rate. The application layer supports both the ATA register command set and PACKET command set, which could drive both the Hard Disk Drive and ATAPI Optical Storage such as CR-ROM, CD-RW, DVD-ROM, DVD-RW, etc. The JMH330 is designed by 0.18um CMOS technology and 64-pin TQFP or QFN or LFQP package.
