Other Parts Discussed in Thread: TIDA-050036
Hello,
We are looking at the TIDA-050036 camera design schematic. The TI953 pins 10(VDDPLL_CAP), 15(VDDSRV_CAP) and 26(VDDD_CAP) have a 1.2V supply connected through ferite L11,L12,L13.
However, in the datasheet of DS90UB953 it is stated "Do not connect to an external supply rail" for those pins.
1) Is there an error or missing information in datasheet of 953?
2) Is there a benefit in connecting those rails to 1.2V?
3) How does the 953 know if it is receiving 1.2V from external supply (954 has pin 46(VDD_SEL) to know this)?
Thank you.
