Wavecrest Patent Granted for TailFit Jitter Separation Algorithm.Business Editors/High Tech Writers EDEN PRAIRIE Eden Prairie A city of eastern Minnesota, a residential suburb of Minneapolis. Population: 57,300. , Minn.--(BUSINESS WIRE)--Nov. 5, 2001 Wavecrest Corporation announces the patent approval of its TailFit(TM) algorithm. This revolutionary technology solves the challenge of jitter A flicker or fluctuation in a transmission signal or display image. The term is used in several ways, but it always refers to some offset of time and space from the norm. For example, in a network transmission, jitter would be a bit arriving either ahead or behind a standard clock cycle separation by accurately and repeatedly dissecting dis·sect tr.v. dis·sect·ed, dis·sect·ing, dis·sects 1. To cut apart or separate (tissue), especially for anatomical study. 2. jitter into two main components, Random Jitter (RJ) and Deterministic Jitter Deterministic jitter (or DJ) is a type of jitter with a known non-Gaussian probability distribution. The other major class of jitter is non-deterministic, or random jitter. (DJ). Released first in 1998, VISI VISI Volar Intercalated Segmental Instability VISI Vision Information Systems, Inc. VISI Ventral Intercalated Segmental Instability software featuring the TailFit algorithm has proven a valuable tool in the hands of design and test engineers worldwide. This TailFit technology is critical in the field of high-speed communications when performing jitter compliance measurement for Gigabit Ethernet, 10Gigabit Ethernet, XAUI XAUI 10 Gigabit Attachment Unit Interface XAUI Extended Auxiliary Unit Interface XAUI XSBI Attachment Unit Interface (IEEE 802.3ae) XAUI Ten Gbps Attachment Unit Interface , Fibre Channel, Infiniband, and other serial data standards. The algorithm enables the calculation of Bit Error Rate (BER (1) (Basic Encoding Rules) A set of encoding rules for ASN.1 notation, which is a method for defining data structures. See ASN.1. (2) (Bit Error Rate) The average number of bits transmitted in error. See BERT. 1. ) as a function of eye closure. The SIA-3000's VISI software calculates bit error rates in seconds as opposed to minutes or hours for conventional equipment. The result is increased throughput, reduced cost of test, and improved time to market. The TailFit algorithm is the cornerstone of Wavecrest's Virtual Instruments(TM) Signal Integrity Software (VISI). Integrated in the newly released SIA-3000 Signal Integrity Analyzer, the VISI tools address the growing needs of the electronics industry to analyze Signal Integrity. "Wavecrest has been the world leader in timing and jitter analysis for over 15 years and continues its leadership role as the trusted jitter experts with this latest patent" said Dennis Petrich, Senior Vice President of Wavecrest. The Wavecrest SIA-3000, the reference standard for signal integrity analysis, is an all-in-one test and measurement instrument with high bandwidth and versatile 10 parallel channel support. It measures data rates up to 4.5 Gb/s with 200 femtosecond resolution. It enables design and test engineers to fully characterize devices faster and easier with accurate and repeatable results. Wavecrest is a provider of innovative and leading-edge electronic test and measurement products for the design and production of electronic and photonic components and systems. Wavecrest signal integrity, jitter, and timing analysis solutions are widely used to measure, diagnose, and test diverse applications. For more information visit www.wavecrest.com. |
