Part Number:LMH1297
Hi Team,
Please allow me to ask you about USB2ANY and SigCon Architect to control LMH1297 on my board.
My LMH1297 is using 2.5V for SMBus pull up voltage.
I would like to control the device with the external PC using SigCon Architect through USB2ANY.
Q1). Does SigCon Architect use the internal pull up in USB2ANY or is it only using USB2ANY as just an open drain output ?
- I believe USB2ANY has internal pull up on it's board which is connected to 3.3V. However, it depends on the software whether this pull up is used or not.
- When started SigCon Architect with USB2ANY connected, I was able to see 3.3V output on the SDA and SCL line. However, I was not able to test the actual communication because it switches to Demo Mode.
Q2). To use SigCon Architect on my board, what do we need to do ?
A). Remove 2.5V pull up on my board and connect USB2ANY to SMBus line. Does this work ?
B). Remove 3.3V pull up inside the USB2ANY and connect it to the SMBus line.
C). Other procedure ?
Best Regards,
Kawai
