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.
