Hi Team,
The customer is using DS90UB913 and DS90UB914. DS90UB913 can receive the signal of VSYNC,HSYNC,DATA and PCLK pins when the external crystal is connected to DS90UB913 . The external crystal is 48MHZ.
For DS90UB914, the customer uses BIST Self-Test, there is a 12MHZ output signal for the VSYNC pin,HSYNC pin and DATA pin and a 24MHZ output signal for
PCLK pin. But there are not any output signals for VSYNC,HSYNC,DATA and PCLK pins in application,not in BIST Self-Test.
Q1: What is the reason? How to solve the issue?
Q2: And the customer need to get the initial setting register for DS90UB913 and DS90UB914.
Q3: If the customer uses the external crystal and PLCK is 36MHZ, how much is external crystal?
Thanks,
Best Regards,5516.TI914.pdf
