Crystal datasheet: Ccrystal = 7pF max ESR = 70kOhm Accuracy
±
20ppm
SAMD21 datasheet: Cxin = 5.5pF Cxout = 5.5pF Cl
≈
1/( (1/5.5pF)+ (1/5.5pF) )
≈
2.75pF
Maximum Load = 12.5pF Maximum ESR = 80kOhm Estimated Cpcb = 0.5pF Estimated load C = 2 (Ccrystal- Cpara - Cpcb) C = 2 (7pF - 2.75pF - 0.5pF) C = 7.5pF Selected in design after verification C= 10/13pF
N
OTE on UART/CDC:
RX/TX on the header denotes the input/output direction of the signal respective to it's source. CDC TX is output from the DEBUGGER. CDC RX is input to the DEBUGGER. TX is output from the TARGET device. RX is input to the TARGET device.
N
OTE on CDC:
TX and RX cross here.
