CY4608M Development Kit - Custom XTAL
The BoM for the CY4608M Development Kit calls for a customised crystal "CRYSTAL 12.000 MHZ 20PF 49US (Drive Level: 600uW, Tolerance: +/- 50ppm)". The only difference I can see between this and a standard ECS-120-20-4 is that the drive level is 600 uW compared with the standard 500 uW. Has anyone used a standard 500 uW crystal in their designs and seen aging (frequency change) problems?
