www..com JMicron/JM20330 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. Features Quick Reference 3.0/1.5 Gbps -3.0% to 0.0 3.3V and 1.8V 2000 V Programmable 2 levels 4 levels 64-pin TQFP All SATA products Mass storage devices Optical storage Dongle bridge Storage system Serial ATA 1.0 Specification compliant Signal Bit Rate Automatic Serial ATA 3.0/1.5 Gbps speed Spread Spectrum negotiation ATA/ATAPI PIO mode 0 to 4 Power Supply .com ATA/ATAPI Ultra DMA of transfer rate 16.7, ESD Protection 25, 33, 48, 66, 100, 133, and 150MB/s. Host and Device ATA/ATAPI LBA48 addressing mode associated with 2-byte sector count Adj. Amplitude Support Serial ATA hot-plug Adj. Pre-emphasis Ultra low power consumption Work for both AC and DC couple between Package the transmitter and the receiver Applications Provide specified OOB signal detection and transmission Support Spread Spectrum Clocking to reduce EMI Support 20MHz, 25MHz, 30MHz or 40MHz Reference Clock Support Partial/Slumber power management Provide adjustable TX signal amplitude and pre-emphasis level Master/Slave support Version 1.0 (c) JMicron 2003.
