Overview

The AC1571 clock chip, a domestically produced clock generator chip, is a PLL based clock generator that uses ADPLL (All Digital Phase Locked Loop) technology to achieve high-frequency and low phase noise performance. It also has low power consumption and high PSNR capability, and can achieve phase jitter performance of less than 0.3ps RMS.

Product Details

Domestic clock generator chipThe AC1571 clock chip is a PLL based clock generator that utilizes ADPLL (All Digital Phase Locked Loop) technology to achieve high-frequency, low phase noise performance, low power consumption, and high PSNR capability. It can achieve phase jitter performance of less than 0.3ps RMS.

The high-precision clock chip manufacturer AC1571 can output differential 100MHz, 125MHz, 156.25MHz, and single ended 33.33MHz CPU clocks, while also outputting 6 channels of 25MHz buffered reference clocks.
