Schematics
- Add serial capacitor on RX/TX line signal (100nF/0402)
- Add 50 Ohms pull down resistors on clock line
PCB
- Place serial capacitors as follow
If design uses Connector : Place serial capacitors only on TX line close to the connector
If design uses onboard link : Place serial capacitor near receiver device pin on TX and RX line
- Place clock pull down resistors as close as possible to clock source (CPU)
- When using Onboard devices, test points shall be placed near receiver (RX) as follows :
