CC2541 32MHZ Crystal Frequency Tolerance

Other Parts Discussed in Thread: CC2541

你好!在使用CC2541过程中遇到关于32MHZ Crystal Frequency Tolerance的问题;

1. 请问量产的时候如何校准频偏?在论坛上看到贵司员工回复“ble不能正常通讯”量产问题时说如果使用的是±10ppm 32MHZ Crystal就不用校准频率,这个±10ppm是指的初始频率特性还是frequency versus temperature characteristics?或者初始频率特性和frequency versus temperature characteristics两者都需要满足±10ppm?

2. 在贵司AN100 - Crystal Selection Guide上推荐Epson Toyocom的FA-128和FA-20H,请告知这两个Crystal的采购代码;

Thanks.
