Low-jitter clock generator with on-chip PLL
The Maxim Integrated MAX31180AUA+ is a single-output clock generator built around an integrated phase-locked loop (PLL) for low-jitter synthesis from a clock or crystal reference. It accepts either a clock or a crystal input and delivers a single clock output at frequencies up to 134 MHz, with a 1:1 input-to-output ratio. The part operates from a 3V to 3.6V supply and is rated over the full industrial temperature range of -40°C to 125°C, making it suitable for outdoor telecom, motor drives, and factory automation environments where temperature extremes are routine.
The 134 MHz maximum output frequency places this part in the mid-range clock-generation tier — fast enough for most Ethernet PHY reference clocks, FPGA configuration oscillators, and microcontroller external clock inputs, but not intended for multi-gigabit SerDes or RF synthesis. The integrated PLL multiplies the input frequency (the part has a multiplier but no divider on the output path), so the designer selects a crystal or reference clock that, when multiplied, lands on the target output frequency. The 1:1 ratio means one input generates one output; there is no fan-out or multiple clock domains inside this package.
Supply and temperature — fit for industrial designs
The 3V to 3.6V supply range is a narrow window typical of 3.3V logic families.
