Storage SATA Port Multipliers SATA Port Selectors SATA PS/PM Combo SATA Host Controllers 2009 EXAR CORPORATION Product Overview The EXStor family includes Port Multipliers (PMP), Port Selectors (PS), Combo devices with integrated PMP and PS, and SATA Host Controllers. All EXStor family devices are certified for SATA 2.6 analog PHY compliance by the University of New Hampshire’s Interoperability Laboratory (UNH-IOL). An example feature set of the Combo XRS10L240 device is found on the next page. All devices are pin compatible, in a 100 pin LQFP package, enabling feature expansion using the initial PCB design. The XRS10L120 and XRS10L210 devices are also offered in the industry’s lowest power, 64 pin QFN package. All SATA Host Controllers support multiple SATA & IDE ports and are AHCI compliant. The Exar / EXStor Family Exar’s EXStor family of storage products provides the combined advantages of the Serial ATA II Active/Passive Port Selector (PS) and Port Multiplier (PMP) implementations for Serial ATA II systems at 3.0 Gbps and 1.5 Gbps. The EXStor family offers lower power and higher reliability devices that support SATA Gen. 2 enhanced features compliant with the latest SATA standards. Device settings have been tailored to achieve full support of Gen-2i and Gen-2m using the default register values. The 2-wire MDIO interface provides access to internal registers enabling advanced features such as spread spectrum clocking, transmit pre-emphasis, and receive equalization. All EXStor PMP/PS devices have been successfully tested for interoperability with all leading host bus adaptor and SATA hard disk drive manufacturers. The EXStor family includes the only combo PS/PMP devices in the industry and the only devices qualified over the full industrial temperature range (-40°C to +85°C). The XRS10L620 is a 32-bit PCI-X/PCI to 2-SATA/1-PATA Host Controller. The XRS10L640 is a PCI-X to 4-SATA Host controller. They allow an embedded CPU with a PCI-X bus to communicate with two/four SATA Devices directly or with up to eight/sixteen additional devices through two/ four 1:4 SATA Port Multipliers (PMP). It uses 3.3V and 1.8V supplies and operates over a wide temperature range of -10°C to +70°C.

Standards Compliance “Best-in-Class” Analog Performance Meets or exceeds SATA Gen-2i and Gen-2m specification allowing for seamless interoperability with all SATA and eSATA-compliant hosts and target devices “out of the box”. Low jitter outputs produce symmetrical, clean output waveforms with improved signal integrity. In addition, programmable transmit pre-emphasis, output amplitude and receive equalization allow the Highest Levels of Integration designer to optimize the parameters for a particular interconnect. This tunability affords the system designer the ability to drive long cables and On-chip functionality includes internal PLL multipliers allowing for backplanes as well as short runs on a compact PCB with optimum BER use of inexpensive external crystals to generate the required high- performance. Also, spread spectrum programmability reduces the peak frequency clocks. Single-supply operation reduces board real estate energy of the fundamental frequency thereby reducing electromagnetic and Bill of Materials cost. Default register settings are sufficient for most emissions for easier FCC compliance. XRS10L620/640 PCI-X to SATA Host Controllers The XRS10L620 is a 32-bit PCI-X/PCI to 2-SATA/1-PATA Host Controller. The XRS10L640 is a 32-bit PCI-X/PCI to 4-SATA Host Controller.
