Part Number: AWR1843BOOST
Other Parts Discussed in Thread: AWR1843
请问AWR1843boost的时钟精度是多少呢?还有AWR1843内部生成的线性调频信号的误差又是多少?
评估板用的是40MHz晶振,频率公差±200ppm,芯片AWR1843的数据手册里面也有写对时钟晶振的要求。
数据手册第67页提到了合成器(线性调频)频率监测功能:
"Synthesizer (Chirp) frequency monitor: Monitors Synthesizer's frequency ramp by counting (divided-down) clock cycles and comparing to ideal frequency ramp. Excess frequency errors above a certain threshold, if any, are detected and reported."
这表明AWR1843内部具有硬件监测机制来检测线性调频信号的频率误差,但数据手册中没有明确给出具体的误差数值或容差范围。
