➀ Microchip开发了一种新型芯片级铯原子钟，结合了恒温晶体振荡器以提高精度和相位噪声。
➁ 该原子钟提供±0.5ppb的初始精度，<0.9ppb/月的频率漂移，以及<±0.3ppb的最大温度引起的误差。
➂ 这款设备有两种版本，适用于不同的温度范围和频率容差，并包括微波合成器和微处理器以实现高级功能。
➀ Microchip has developed a new chip-scale cesium atomic clock combined with an oven-controlled crystal oscillator for improved accuracy and phase noise.
➁ The atomic clock offers initial accuracy of ±0.5ppb, frequency drift of <0.9ppb/month, and maximum temperature-induced errors of <±0.3ppb.
➂ The device comes in two versions with different temperature ranges and frequency tolerances, and includes a microwave synthesizer and a microprocessor for advanced functionality.
