Low-Voltage I Cs Enable Precise Re-Synchronization and Fan-Out/Distribution Across Multiple Applications
SANTA CLARA, Calif.—(BUSINESS WIRE)—June 28, 2005— Alliance Semiconductor Corporation (Nasdaq: ALSC), a leading worldwide provider of analog and mixed signal products, high-performance memory products, connectivity and networking solutions for the communications, computing, embedded, industrial and consumer markets, today announced the expansion of its Analog and Mixed Signal product portfolio with the availability of its newest families of high-performance Zero Delay Buffers (ZDB's) and Non-Zero Delay (NZDB) Buffers. The ASM5000 family of PLL-based ZDB's and the ASM2000 family of non-PLL-based NZDB's are designed to address the precise, high accuracy and high-performance (greater than 250MHz) clocking needs of various data communications, networking, telecommunications, industrial and many consumer systems.Fast edge rates (less than 1nS), low propagation delays (50-500pS) high accuracy (duty cycle stability & jitter) along with very high frequency support (greater than 250MHz), characterize both families of these precision buffers. The devices are designed to support one or two 50 ohm transmission lines.
This expansion includes many of the standard high performance (250MHz+) buffers currently in volume demand. The table below details the 3.3 / 2.5V Low Voltage NZDB's devices in this initial release. The second table details the Low Voltage ZDB's. Alliance Semiconductor expects to continue the product expansion as the line continues its evolution into high performance, very low voltage, high accuracy applications.

These precision Non PLL based products support either 2.5 or 3.3V power supplies and provide support from DC to well in excess of specification of 250MHz, with up to 18 outputs for precise fanout and distribution of the clock signal with very low prop delay and output skews. Many of these products (ZDBs and NZDBs) support a "split-rail" design that provides for either 3.3V or 2.5V LVCMOS outputs for conversion / translation of either a LVCMOS or LVPECL input to LVCMOS, and thus allows for use across multiple platforms. Single and multiple output bank configurations are supported as well.

This high-performance family of Low Voltage Zero Delay Buffers provides support for frequencies from DC to beyond specification (greater than 250Mhz Vs the 200MHz spec) with fan-outs of 12 and 14, and very low propagation delays (Tpd and Tskew) for precise re-synchronization (zero delay) and accuracy. These features coupled with fast edge rates and low jitter, enable the designer to maximize their timing budgets with minimal error budget contribution.
Packaged in 32 and 52 pin LQFP and TQFP packages, Alliance offers both commercial and industrial temperature grades, with standard tin-lead / Pb free - RoHS and/or Green compliant products.
According to Mark Sherwood, director of Marketing for the Alliance Mixed Signal Business Unit, "This is a significant introduction and roll out for Alliance Semiconductor. The combination of these Low Voltage High Performance ZDB's and LVNZDBs will add significantly to the current offering from Alliance Mixed signal and provides entry into the High-end LVCMOS clock market.
"This release allows Alliance Semiconductor to support all key aspects of the clock tree i.e. clock synthesis, frequency generation, clock signal distribution and re-synchronization. With this new addition, Alliance Semiconductor's Mixed Signal Group is now well positioned in clock and timing with a Very wide, in-depth and comprehensive portfolio into the high accuracy and performance applications segments."
Target applications include routers, switches, hubs, base stations and redundant array of independent disks (RAID) storage arrays, as well as specific applications in industrial and some consumer applications.
Samples are available today with initial pricing set at $3.00 - $3.50 in 1K quantity. Full data sheet/product specifications and a complete cross reference guide are available online at www.alsc.com
