It is a year-round resort and a booming military, technological, and commercial city. , Colo.--(BUSINESS WIRE)--July 15, 1996--Building on its long tradition of industry leadership in SCSI SCSI in full Small Computer System Interface Once common standard for connecting peripheral devices (disks, modems, printers, etc.) to small and medium-sized computers. SCSI has given way to faster standards, such as Firewire and USB. technology, Symbios Logic Symbios Logic was a manufacturer of SCSI host adapter chipsets and disk array storage subsystems. It was a wholly owned subsidiary of Hyundai Electronics America. It was originally a division of NCR Corporation, before NCR's takeover by AT&T. AT&T sold off the division to Hyundai. Inc. announced today its support of low voltage differential (hardware) Low Voltage Differential - (LVD) A method of driving SCSI cables that will be formalised in the SCSI-3 specifications. LVD uses less power than the current differential drive (HVD), is less expensive and will allow the higher speeds of Ultra-2 SCSI. LVD requires 3. (LVD See LVDS. LVD - Low Voltage Differential ) signaling for use with the Ultra2 SCSI standard. This draft standard is being developed by the X3T10 SCSI Parallel Interface 2 (SPI-2) working group charged with extending the viability of parallel SCSI I/O (Input/Output) The transfer of data between the CPU and a peripheral device. Every transfer is an output from one device and an input to another. See PC input/output. I/O - Input/Output technology into the twenty-first century. LVD is a robust design methodology that improves power consumption, data integrity, cable lengths and support for multiple devices, while providing a migration path for increased I/O performance. Symbios Logic's implementation of LVD transceivers is called LVDlink which will meet all of the requirements of the SPI-2 standard including support for Universal LVD SCSI. With the introduction of its new LVDlink technology, Symbios Logic has implemented LVD as the basis of its transceiver technology, providing the signal integrity and data reliability expected from high voltage differential (hardware) High Voltage Differential - (HVD) Differential SCSI scheme that has been in use for years. The terminators run on 5 Volts DC. See also LVD. signaling but at a much lower solution cost. Symbios Logic's LVDlink transceivers also reduce the power needed to drive the bus, lower the amplitude of noise reflections, and allow for higher transmission frequencies. The differential signaling does an excellent job of canceling out signal noise due to external sources allowing systems to utilize up to 12 meter cable lengths while attaching up to 16 devices to an LVD SCSI bus. "As one of the principal pioneers in the development of the SCSI I/O standard, Symbios Logic has consistently supported all efforts to improve the performance of SCSI technology," said Harry Mason, Director of SCSI Marketing, Symbios Logic, and Chairman of the SCSI Trade Association The SCSI Trade Association, or SCSITA, is an industry trade group which exists to promote the use SCSI technology. It was formed in 1996 [1]. As of 2006, major members include Adaptec, HP, Intel, LSI Logic, Seagate, and IBM [1]. . "With the announcement of our LVDlink transceivers and the adoption of LVD technology, we will not only improve the performance of our SCSI technology but also increase the life span of our customers' significant investments in SCSI technology. LVDlink transceivers will allow system developers to significantly improve system performance without having to invest in the wholesale re-creation of interface solutions that is necessary with a new I/O standard." Symbios Logic LVDlink transceivers coupled with the performance features of Ultra2 SCSI will boost 16-bit synchronous data Synchronous data Information available at the same time. To test option-pricing models, the price of the option and of the underlying should be synchronous and reflect the same moment in the market. transfer rates from current speeds of 40MB per second (Ultra SCSI), to 80MB per second (Ultra2 SCSI). In addition, the low voltage/current component of the LVD bus allows transceivers to be implemented in 3.3V CMOS (Complementary Metal Oxide Semiconductor) Pronounced "c-moss." The most widely used integrated circuit design. It is found in almost every electronic product from handheld devices to mainframes. that enables integration into standard SCSI controllers eliminating the need for expensive external high voltage differential transceivers. The universal features of the LVDlink transceivers allow the controller to operate in legacy SCSI modes, such as single-ended and high voltage differential (via external transceivers), while assuring forward compatibility with LVD-based Ultra2 SCSI devices. This is what makes the LVDlink methodology very robust as well as the standard transceiver technology interface for future high performance SCSI offerings from Symbios Logic. Symbios Logic creates storage management and peripheral connection solutions and provides a full spectrum of products for these solutions, including integrated circuits, host adapter boards and subsystems as well as supporting software drivers and utilities. The Company focuses on developing technology partnerships with its customers and vendors, including original equipment manufacturers and resellers in the networked computing, peripheral and communications markets.
