JMB362 supports both ahci and legacy ide controller to inc rease system feasibility, including native command queuing, atapi device, port multiplier with command-based switching, hot plugging like usb and esata (external sata) connection on sa ta port to enhance sata ii capability. it features pci express bus and serial ata ii interfac e to express high performance storage devices. JMB362 supports pci express to make trace length ca n be up to 8 (20.3cm). although the maximum length is up to 8 inch, the trace length is as short as possible on real application. JMB362 supports sata ii gen1m and gen2m for esata a pplication through programmable output swing control and receiver sensitivity contr ol. from hardware design view, esata trace can be up to 15 (38.1cm) with proper layout style and some examples are list in following section. although the maximum length is up to 15 inch, the t race length is as short as possible on real application. of course, esata hdd connected with 2m esata cable must be supported according to sata-io definition. feature compliance compliant with serial ata ahci (advanced host controller interface ) spec. reversion 1.0 compliant with bus master programming interface for ide ata contro llers revision 1.0 compliant with pci express base spec. revision 1.0a compliant with serial ata high speed serialized at attachment spec . revision 1.0a compliant with serial ata ii: extensions to serial ata 1.0a revisi on 1.1 compliant with gen1i, gen1m, gen2i and gen2m serial ata ii: electrical spec. revision 1.0 overall integrated 1-lane pci express phy and 2-port sata i i phy integrated two pll for both pci express bus and sat a ii interface output swing control and automatic impedance calibr ation for both pci express and sata ii phy supports a slave smbus interface (follow system management bus specification revision 1.1 ) fabricated 0.18um/3.3v umc cmos standard logic proc ess with 1.8v and 3.3v available in 48-pin qfn package pin compatible with jmb360 (1-port sata ii host con troller) www.datasheet.co.kr datasheet pdf - http://www..net/
