Cirrus Logic's CS61884 Octal T1/E1/J1 Line Interface Unit Reduces BOM Costs for Telecom Equipment OEMS.Business Editors & High-Tech Writers AUSTIN, Texas--(BUSINESS WIRE)--June 11, 2002 Patented Matched Impedance Technology Reduces Power Consumption, Component Count, and Overall BOM Costs Cirrus Logic (Nasdaq:CRUS), a premier supplier of high-performance analog and DSP (1) (Digital Signal Processor) A special-purpose CPU used for digital signal processing applications (see definition #2 below). It provides ultra-fast instruction sequences, such as shift and add, and multiply and add, which are commonly used in math-intensive chip solutions for consumer entertainment electronics, announced today that it is in full production of the new CS61884 T1/E1/J1 Octal A numbering system that uses eight digits. It is used as a shorthand method for representing binary characters that use six-bits. Each three bits (half a character) is converted into a single octal digit. Okta is Greek for 8. Line Interface Unit (LIU LIU Linköpings Universitet (Sweden) LIU Long Island University (New York) LIU Line Interface Unit LIU Lightguide Interconnection Unit (AT&T) LIU Laugh It Up ), the latest and most feature-rich addition to its LIU product family of telecommunications solutions. The CS61884 builds on Cirrus' patented matched impedance technology, which completely eliminates the need to change external components between 75-ohm, 100-ohm and 120-ohm mode designs. The simplified, single circuit design reduces component count and the manufacturing bill of materials (BOM) for telecommunication customers. This allows manufacturers to support all major international telecommunications protocol standards in one "universal T1, E1, J1" functional line card while providing savings on materials, engineering, qualification and procurement efforts. The CS61884 builds on the tremendous success of Cirrus' LIU family and continues a decade-long legacy of outstanding telecommunications solutions. "As high bandwidth optical technology continues to drive telecom network expansion, the new Cirrus CS61884 Octal LIU provides the high port densities required by our customers," said Lew Paceley, vice president of marketing for the Crystal Products Division. "Our new Octal LIU brings industry standard compatibility with the added benefits of our matched impedance technology." The CS61884 integrates eight full-featured LIU channels in an industry standard footprint and firmware compatible IC. Each channel has complete receiver and transmitter circuitry including crystal-less path-selectable 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 attenuation Loss of signal power in a transmission. Attenuation The reduction in level of a transmitted quantity as a function of a parameter, usually distance. It is applied mainly to acoustic or electromagnetic waves and is expressed as the ratio of power densities. , full encoder/decoder circuitry, Loss of Signal detection, and Alarm Indication Signal “AIS-P” redirects here. For the data packet protocol, see Automatic Independent Surveillance-Privacy. Alarm indication signal (AIS) is a signal transmitted by a system that is part of a concatenated telecommunications system to let the receiver know that some warnings. In addition, there is an Arbitrary Waveform Generator An arbitrary waveform generator (AWG) is a piece of electronic test equipment used to generate electrical waveforms. These waveforms can be either repetitive or single-shot (once only) in which case some kind of triggering source is required (internal or external). allowing user-customized transmit pulse shapes. Pricing and Availability The CS61884 is one of three new Octal port additions to the LIU family of devices, the others being the CS61881 Octal E1 AFE (Apple File Exchange) An earlier Macintosh utility that converted data files between Mac and PC formats. It also included a file translator between IBM's DCA format and MacWrite. and the CS61880 Octal E1 LIU. All three are currently shipping in volume production. The CS61884 is available in 144-pin LQFP See QFP. and 160-pin FBGA FBGA Fine-Pitch Ball Grid Array FBGA Fine Pitch Bga FBGA Fine Line Bga packages. CS61884 pricing starts at $25.03 for the LQFP in 10,000 OEM (Original Equipment Manufacturer) The rebranding of equipment and selling it. The term initially referred to the company that made the products (the "original" manufacturer), but eventually became widely used to refer to the organization that buys the products and quantities.
