Hi,
Our customer considers the configuration of the power supply pin to be interchangeable with AM5718 in AM5728.
Some constitution of AM5728 are different from AM5718 with a power supply pin as follows.
AM5718
vdd_dsp…K10 / K11 / L10 / L11 / M10 / M11
vdd_iva…J13 / K12 / K13 / L12 / M12 / M13
NC…U18/ U19/ V18/ V19
AM5728
vdd_dsp…J13/ K10/ K11/ K12/ K13/ L10/ L11/ L12/ M10/ M11/ M12/ M13
vdd_iva…U18/ U19/ V18/ V19
What kind of step should the pin take to keep compatibility in AM5718 and AM5728?
As for the U18/ U19/ V18/ V19 pin, AM5718 becomes the NC processing.
Even if those pins input a power supply same as vdd_iva, do they not have any problem?
Our customer is not going to use IVA and the dsp. In Table 5-6 AVS and ABB Requirements per vdd_* Supply of the data sheet of AM5718, the supply voltage has mention of AVS being necessary and being OPP-dependent.
When they do not use them, please tell me the voltage value that it should supply.
Does vdd_iva,vdd_dsp not have any problem with a common power supply?
Best Regards,
Shigehiro Tsuda
