TriQuint Semiconductor Introduces the TQ8025 Crosspoint Switch; The TQ8025 Fast-Configure 2.5Gb/s 16x16 Crosspoint Switch Offers Increased Capacity and Throughput.HILLSBORO, Ore.--(BUSINESS WIRE)--Aug. 19, 1998--TriQuint Semiconductor, Inc. introduces the TQ8025, a fully differential 16x16 crosspoint switch Also known as a crossbar or NxN switch, it is a switching device that provides for a fixed number of inputs and outputs. For example, a 32x32 switch is able to keep 32 nodes communicating at full speed to 32 other nodes. integrated circuit integrated circuit (IC), electronic circuit built on a semiconductor substrate, usually one of single-crystal silicon. The circuit, often called a chip, is packaged in a hermetically sealed case or a nonhermetic plastic capsule, with leads extending from it for (IC) which operates at data rates up to 2.5 gigabit/second per port. The TQ8025 is the first 16x16 crosspoint switch supporting an aggregate, non-blocking data rate of 40Gb/s with a configuration time of 80ns and less than 50ps 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 . The TQ8025 offers designers a new level of performance and features to address the growing demands for switched serial links in LAN (Local Area Network) A communications network that serves users within a confined geographical area. The "clients" are the user's workstations typically running Windows, although Mac and Linux clients are also used. , WAN, Storage Area Networks (SAN), SONET/ATM and High-Definition TV See HDTV. (HDTV (High Definition TV) A set of digital television (DTV) standards that offer the highest resolution and sharpest picture. Although some HDTV sets are available in standard (rather square) screen sizes, the overwhelming majority of sets are wide screen, which eliminates ) applications. The TQ8025/s 16x16 configuration provides 700% more capacity than competing 2.5Gb/s devices and 60% greater capacity than competing 1.5Gb/s devices. The TQ8025's fast configuration time of 80ns significantly reduces the time required to configure all 16 channels, dramatically increasing the performance of packet switching systems. "Increasing the serial data rate to 2.5Gb/s and reducing the configuration time are critical to improving capacity, throughput, and latency in switched serial links. When coupled with TriQuint's new TQ9525 2.5Gb/s Ultra-Fast-Locking Transceiver, designers have the key components of a 40Gb/s high-throughput switching system," said Dave Drummond, Marketing Manager for TriQuint's Datacom and Switching Products. PERFORMANCE The TQ8025, like all of TriQuint's crosspoint switch products, uses a true non-blocking architecture of 16 fully independent 16:1 multiplexers. The user can independently program each output to any input without concern for internal blocking or degradation of data rate or performance due to switch loading. System designers will appreciate the fully differential data path for superior noise rejection and minimum signal distortion including very low jitter, crosstalk, and skew (1) The misalignment of a document or punch card in the feed tray or hopper that prohibits it from being scanned or read properly. (2) In facsimile, the difference in rectangularity between the received and transmitted page. . The high-speed data inputs and outputs are PECL/CML level with on-chip 50 Ohm input termination to optimize signal fidelity and simplify circuit board layout. Control inputs are TTL (1) (Time To Live) A parameter in a network packet that sets a time limit to its validity. In order to prevent an IP packet from propagating endlessly through the network, the value in the TTL field is reduced by each router. level. The TQ8025 incorporates two programming modes providing design flexibility to best match the application requirements. Both program modes use two-stage storage registers allowing the loading of new configurations without disruption to data moving through the device. The sequential program mode, used on all of TriQuint's crosspoint switch products, is the most flexible, and is well suited for applications such as video routing that typically does not require the fast configuration rates. New channel configuration is sequentially loaded into the appropriate channel's storage register. Any number of channels can be sequentially loaded with a new configuration. The fast-configure program mode is ideally suited for applications that continuously change the configurations on a packet-by-packet basis, such as a network switch. Using a 16-bit parallel input, the TQ8025 loads four 16-bit words into the first-stage storage registers with an external 50MHz (MegaHertZ) One million cycles per second. It is used to measure the transmission speed of electronic devices, including channels, buses and the computer's internal clock. A one-megahertz clock (1 MHz) means some number of bits (16, 32, 64, etc. clock input. The configurations for all 16 ports are loaded in 80ns. Complementing the fast-configure program mode, the TQ8025 can automatically configure the switch core following the loading of the four 16-bit program words. The TQ8025 provides two output pins, driven by a two-bit counter that is clocked by the 50MHz parallel-load clock. The outputs can be used to sequentially address an external storage register containing the 16-bit program words. APPLICATIONS The TQ8025 offers a new level of performance with features well suited for the growing number of applications that require high-bandwidth or high-throughput switching. Such applications include LAN, Internet Protocol (IP), WAN, and Storage Area Network (SAN), which need the bandwidth and fast programming to address the growing demand for increased switch capacity and throughput, which also require reduced latency. For serial High-Definition TV (HDTV) switch applications, the TQ8025's bandwidth and signal fidelity offer un-matched performance and system design margin. PACKAGE The TQ8025 is available in a 132 pin thermally enhanced ceramic quad flat pack (CQFP See QFP. ) package. PRICE AND DELIVERY Pricing is $265 each at quantity of 1,000.
