Dear Mr./Ms.
1. When the datasheet says that recommended operating condition, IDD, VDDRA/B/C/D_LS is 168mA, does it means that the total current of all channel is 168mA or maybe it refers to a one channel only?
2. Same question as above applies also for VDDRA/B/C/D_HS and VDDO[3:0].
3. In case the above answer is that the values are the sum of all channels, what would be the supply current in case that only one channel is enabled and the other three are disabled and no clock is supplied to them?
4. The EVM uses LDO to step down the various voltage supplies, does it really needed or perhaps a switching regulators will do the work? Please refer to each of the supplies.
Many thanks,
Uzi
