Hello
Description of "drive level 600 uW" of the 12 MHz crystal oscillator in the data sheet.
How should we interpret this value? Is there a basis for the description of "Drive Level: 600 uW" in the BOM list below?
>CRYSTAL 12.000 MHZ 20 PF 49 US (Drive Level: 600 uW, Tolerance: +/- 50 ppm) --- ECS-120-20-4 ----
Best Regards
Arai

We have been recommending to use high drive level (600-μW) crystal on AN72332.
The value of 600-μW has a margin and ECS-120-20-4 which has maximum 500-μW can work without any problems.
The important point is that Power dissipation < drive level formula is established.

Hi Arai-san,
Crystal drivel level is the power that is driven into the crystal.
For more information, kindly refer to "3.2.1 Crystal Drive Level" on AN72332.

CY4608で使用されている、ECS-120-20-4の水晶自体のドライブレベルが 最大で0.5mWと記載されている為、
AN72332に記載されている”600-μW minimum drive level”との関連付けについてご説明頂けませんでしょうか?
