Tuesday May 12, 6:32 am Eastern Time Company Press Release IMP, Inc. Adds to Data Communication Offering SCSI Ultra2 Multimode LVD/SE Terminators Extend Bandwidth to 80MBytes/SEC SAN JOSE, Calif.--(BUSINESS WIRE)--May 12, 1998--IMP, Inc. (NASDAQ:IMPX - news) today announced the expansion of its SCSI (Small Computer Systems Interface) data communications interface Integrated Circuit (IC) family with the addition of two new Low Voltage Differential (LVD) Multimode Ultra2 SCSI Terminator ICs, the IMP5241 and IMP5242. SCSI is an intelligent interface standard that controls the flow of data between the central processing unit of a personal computer (PC) and its peripherals and extends server-style data transfer rates to the PC arena. These LVD SCSI devices represent the second family of circuits to result from the technology strategic alliance signed with Linfinity Microelectronics, Inc. in 1997. Both companies will offer these products fabricated from the same mask set. This insures identical in-system performance from two vendors. In addition, the IMP5241 is compatible with the DS2118M LVD terminator from Dallas Semiconductor. The new IMP5241 and IMP5242 multimode SCSI terminator ICs conform to the Ultra2 Low Voltage Differential SPI-2 specification developed by the T-10 standards committee. The SPI-2 specification requires the use of a low voltage differential signaling technique to enable data transfers at speeds up to 80 megabytes per second over 12-meter cable lengths. According to, Adaptec Inc. [Nasdaq:ADPT - news], the industry's leading supplier of SCSI host adapters for desktop PCs and servers, the demand for increased bandwidth has allowed SCSI interfaces to increase their penetration of the market from 6% in 1992 to 12% in 1997. This new version will enable SCSI solutions to continue to increase their share of this fast growing market. ''Designed for the emerging Ultra2 SCSI market, our newest terminators provide further evidence of our solid commitment to the SCSI peripheral industry,'' said Barry Wiley, IMP Vice President of Marketing, Sales and Applications. ''By staying ahead of the industry's LVD needs, we continue to support our customers' preparation for tomorrow's market with the latest IC designs.'' ''IMP has extensive experience supporting computer peripheral manufacturers, such as hard disk drive and tape storage companies who will be using these new terminator products,'' added Barry Wiley. ''Our business is focused on the needs of these customers, and we have built-up our capability to manufacture the high volumes that the peripherals market requires.'' In addition to meeting Ultra2 specifications, the new multimode terminators also ensure backward compatibility with legacy Single Ended (SE) SCSI-1, 2, 3, and Ultra (FAST-20) specifications. The terminators provide both auto-selectable LVD differential mode and single ended termination. The auto-select feature enables these intelligent terminators to function in LVD differential mode, or if a legacy peripheral operating in single ended mode is detected, reconfigure the system for single-ended mode. Each of the nine channels has completely isolated circuitry. This not only enhances reliability, but also provides a 35MHz bandwidth, typically 100 times faster than traditional SCSI terminator designs. The high bandwidth insures Ultra2 performance, up to 80 megabytes per second, while providing a clear migration path to Ultra-3 and beyond. Ultra-3 will increase data transfer rates to 1.28 gigabits per second (160 megabytes). All IMP multimode devices feature auto-selectable LVD or SE (single-ended) termination, high-speed response without external capacitors and a high bandwidth driver that reduces channel-to-channel noise and crosstalk. Automatic Mode Selection Proper mode selection is automatic. If DIFFSENSE is below 0.5V single-ended operation is selected and if between 0.7V and 1.9V LVD operation is selected. Outputs are placed in a high-impedance state when DIFFSENSE is above 2.4V. A sleep or disable mode reduces supply current to 10 microamperes maximum and puts the DIFFSENSE and outputs in a high impedance state. Master/Slave Operation Driving the Master/Slave pin LOW disables the on-board DIFFSENS reference, allowing the use of an external master reference. If the Master/Slave pin is allowed to float or is driven HIGH, the internal DIFFSENSE reference is active. External Capacitors Eliminated Other IC terminators require an external RC delay network to accommodate the100mS delay it takes between changes on the DIFFSENSE line and changes on their outputs. The IMP multimode parts include an internal digital counter that eliminates the external RC network. In the LVD mode, a fast buffer instead of regulators that require external capacitors supplies the line common mode voltage. In SE mode, the devices operate in a nonlinear adaptive mode for close matching to actual SCSI bus impedance. Unlike most LVD multimode terminators, no external capacitors are required for references or regulators on the IMP multimode devices. Only a termpower bypass capacitor is required. Pricing for the IMP5241 and IMP5242 in quantities of 1,000 is $3.41 for the 24-pin TSSOP package and $3.56 for the 36-pin SSOP package. Production is scheduled to begin in June 1998.
