描述 Description

CREATE AND SAMPLE YOUR CUSTOM ZL30263 HEREThe miClockSynth ZL30263 high-performance, any-rate multiplier and clock generator device simplifies board design by generating ultra-low-jitter clock signals from a single crystal or crystal oscillator while generating additional independent frequency families.With two independent frequency families on one chip, best-in-class jitter performance, and fractional-N APLL with both a fractional and integer divider. The ZL30263 creates a complete clock-tree, improving design reliability, reducing bill of materials (BOM) cost, and simplifying design by replacing multiple crystals and peripheral timing components.
