Will the device be effected if the power squence of 1.8V-> 3.3V is not implemented .
We had not implemented the power up sequence and now we have implemented the sequence .
Half of the boards are not working properly
: There are not able to lock on to the HDMI input and the outputs are stable
- Clock is not constant , cycle period is long here and there
On checking without power OFF ,checking the resistance between HDMI input and GND we find ,
Proper working device : 4 pair HDMI input pin was 7 Mohm
Not properly working device : some 10 - some 100 ohm
With best regards and wishes
