JM20330 datasheet


The Serial ATA Bridge 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 main applications are for legacy IDE storage devices connecting to newer chipset supporting serial ATA, such as the iCH5 south bridge of Intel chipset, and serial ATA IDE storage devices connecting to traditional IDE south bridge.




1. 0.18um CMOS technology.
2. Serial ATA 1.5Gbps (Gen. 1) PHY.
3. Spread-Spectrum Clock (SSC) technology.
4. 1.8V and 3.3V power system.
5. 25MHz external reference clock.
