Hi Champs,
My customer is evaluating EMI test with below setup and condition.
-
Sensor Camera + DS90UB913A + coax cable(2m) + DS90UB914
-
48MHz clock is supplied to GPIO3 and 1/2 divided clock is fed to Sensor Camera.
-
DS90UB913A is configured as 12bit High Frequency mode.
There is spurious around 500MHz, and the customer needs to identify the cause of the spurious within 19th in Japan time.
Measurement was done under DS90UB914 being shielded condition, so Sensor camera or DS90UB913A or coax cable would be the source of the spurious.
Q.1)
According to the configuration, Line rate is calculated as 1.344GHz.
Can you guess the root cause of 500MHz spurious?
Q.2)
Can you provide EMI test result and test setup to confirm no fatal spurious could not be seen under proper setups?
Best regards,
Nobuo
