JM20330

Serial ATA Bridge Chip

Description

JMicron’s JM20330 is a single chip solution for serial and parallel ATA translation. It includes the

Serial ATA PHY, Link, Transport, and Parallel ATA (application layer) controller. The Serial ATA

physical, link, and transport layers are compliant to Serial ATA 1.0. JM20330 supports a 1.5GHz data

rate, and scalable to 3.0 GHz data rate by directly doubling the internal clock source. The application

layer supports both the ATA register command set and PACKET command set, which could drive both

Hard Disk Drive and ATAPI Optical Storage such as CR-ROM, CD-RW, DVD-ROM, DVD-RW, etc.

The Serial ATA and the Parallel ATA application layer support both host and device operation and can

be configured through a single pin.
