Alliance Semiconductor Corp. (Santa Clara, CA), a provider of analog and mixed-signal products, high-performance memory products and systems solutions for the communications, computing, embedded, industrial and consumer markets, announced the availability of its AS80M25XX Series of dual-phase, locked-loop (PLL), clock chips, which allow for third-party clock configuration while reducing electromagnetic interference at the clock source.
The AS80M25XX Series are I2C configurable, which means all the functional parameters of the devices can be configured from an external I2C master unit through the I2C bus. Users can optimize the device configuration by writing to the device through the I2C bus and then validating the results "in-system." Alliance also provides the option of hard-coding the final configuration by factory programming. The user is provided the flexibility of synthesizing any output frequency from any input frequency source within the operating ranges of the device.
The AS80M2516A includes two on-chip PLLs with four frequency outputs (two per PLL); an input-frequency range of 6Mhz to 80Mhz in spread spectrum mode or 2Mhz to 200Mhz in non-spread spectrum mode; an output-frequency range of 4Mhz to 140Mhz; a supply voltage of 3.3V, a programmable spread range and type of modulation (center or down) and type of profile, and an incorporated power-down feature.
The AS80M2516 is priced at $3.50 in 10,000-unit quantities and is available now in sample quantities.
