Skyworks Solutions Inc. Si5332 6/8/12-Output Clock Generators

Skyworks Solutions Inc. Si5332 6/8/12-Output Any-Frequency Clock Generators are ideal for replacing multiple clock ICs and oscillators with a single device. The generators are based on proprietary MultiSynth™ flexible frequency synthesis technology, which enables any frequency synthesis on any output up to 250MHz. The Si5332 series generates a combination of output frequencies with excellent jitter performance (<400fs RMS). The architecture enables a single device to generate a wide range of integer and non-integer-related frequencies on as many as 12 differential clock outputs with 0ppm frequency synthesis error. Skyworks Si5332 6/8/12-Output Any-Frequency Clock Generators offer multiple banks of outputs that can each be tied to independent voltages, enabling usage in mixed-supply applications. The signal format of each clock output is user-configurable.
