Hi Team,
Customer uses PGA2505 on the new project. Would you please review and provide comment for the questions?
1. customer used PGA2505 and PGA2505 was controlled this chip via SPI bus;
2. PGA2505 will affect the system SPI bus in our system as follows:
a. R290 mounted, System SPI_CLK's high level is about 1V(abnormal);
b. After remove R290, System SPI_CLK's high level recovered to 3V3;
Have you met this issue before? or Would you give us some comments about it?
BR,
SHH
