7.2 MX8731A application circuit
Note:
1. C1, C2, R4 as close USB/PS2 line solder pad on PCB as possible, PCB layout should be designed
in such a way as to ensure that the VDD is stable and pass through RC filter.
2. The capacitance C3, C4 & C5 have to close to IC.
3. D+/CLK and D-/DATA signal line have the short trace to IC.
4. Recommend to have ground grid on the PCB periphery.
5. Components in dotted line are used for EMC issue.
