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.
