Alliance Samples Dual PLL Clock for Digital Projectors; Single Chip Timing Solution for Projection Market.SANTA CLARA, Calif. -- Alliance Semiconductor Corporation (Nasdaq:ALSC ALSC Association for Library Service to Children ALSC Adirondack Lakes Survey Corporation ALSC Afloat Logistics and Sealift Capability ALSC American Lumber Standards Committee, Inc. ALSC Advanced Logistics Systems Center (AFMC) ), a worldwide provider of analog and mixed signal products, high-performance memory products and systems solutions for the communications, computing, embedded, industrial and consumer markets, today announced samples availability of the ASM (1) (Association for Systems Management) An international membership organization based in Cleveland, Ohio. Founded in 1947 and disbanded in 1996, it sponsored conferences in all phases of administrative systems and management. 3P2853A, a dual PLL PLL - phase-locked loop Clock Synthesizer supporting applications such as PC peripheral devices, consumer electronics, and embedded controller systems such as Texas Instrument's DLP (Digital Light Processing) A data projection technology from TI that produces clear, readable images on screens in lit rooms. DLP is used in all types of projection devices, from data projectors that weigh only a few pounds to large rear-projection TVs to electronic (TM) Technology. The ASM3P2853A is a versatile spread spectrum frequency clock generator that reduces electromagnetic interference (EMI (ElectroMagnetic Interference) An electrical disturbance in a system due to natural phenomena, low-frequency waves from electromechanical devices or high-frequency waves (RFI) from chips and other electronic devices. Allowable limits are governed by the FCC. ) at the clock source. This allows for significant system cost savings by reducing the number of circuit board layers and shielding that is required to pass EMI regulations. Spread spectrum clocking technology can virtually eliminate EMI filter networks and ferrite beads, with an added benefit that circuit board traces can be routed more effectively, enhancing design flexibility and layout. The ASM3P2853A modulates the output of the PLL in order to spread the bandwidth of the synthesized clock, thereby decreasing the peak amplitudes of its harmonics. This results in significantly lower system EMI compared to the typical narrow band signal produced by oscillators and most clock generators. Lowering EMI by increasing a signal's bandwidth is called spread spectrum clock generation. "Spread Spectrum Clocking is definitely a good insurance policy," said Nelson Arata, product marketing manager for Alliance's Analog and Mixed Signal business unit. "Experienced designers know that EMI can be an 11th hour nightmare. Spread Spectrum capability will help the system designer sleep better knowing that his system has up to 6dB of additional EMI clearance." Packaged in an 8 pin SOIC (Small Outline IC) A small-dimension, plastic, rectangular, surface mount chip package that uses gull-wing pins extending outward. See gull-wing lead, SOJ and chip package. , the ASM3P2583A provides a 50 MHz (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. Spread Spectrum clock and a Low Jitter 48 MHZ USB USB in full Universal Serial Bus Type of serial bus that allows peripheral devices (disks, modems, printers, digitizers, data gloves, etc.) to be easily connected to a computer. clock from a 25MHZ crystal source. Samples are available today, with initial pricing set at $1.50 in 1K quantities. Full data sheet/product specifications are available online at www.alsc.com.
