Hello Team,
can you help in getting the internal clock to SYNC OUT, please? What are the correct settings in the Fusion GUI?
With the above setting there is no clock at Pin 19 (testpoint EN_VOUT_B, not connected to gnd via S2).
How to apply an external clock via SYNC / RESET# / BVR_EN Pin? I guess R36 and R142 have to be removed for external clock?
Thank you and Best Regards,
Hans
Hi Hans,
You can refer to the following excerpts from the datasheet to see how to configure the SYNC pin.
Thank you,
Dhanya Prem
Hello Dhanya Prem,
Hans was asking me to clarify the issue:
You can find the schematic in question here: /cfs-file/__key/communityserver-discussions-components-files/196/BMC051A.pdf
Desoldering R36 and R142 disconnects TP12 "EN_VOUT_B" from 3.3V, where I want to measure the clock output. The switch S2 is disabled, connecting pins 2 and 3.
Concerning additional clock settings in the NVM: Where and how do I access these settings within the GUI? The only setting I have access to is in the "Systems Configurations" tab, like in the screenshot by Hans. Are these additonal register settings hidden under the "advance" config level? Can you perhaps provide the password to unlock this feature?
Regards
Chris
Hi Christian,
You could try that to see if you are able to measure a clock output.
In order to access the lower-level GUI, you can do that by going under Tools > SMBus_I2C_SAA tool. Kindly refer to the device's technical reference manual while accessing the commands through the lower-level GUI to make sure you are using the right format (Read Word/Read Byte etc.).
Thank you,
Dhanya Prem
