Hello,
The DW1000 datasheet shows VDDBAT current requirement is lumped in with 5 other supply pins, VDDPA1, VDDPA2, VDDLNA, VDDAON, and VDDIOA.
But you recommend that when using a TCXO, the VDDBAT pin is to be supplied with the same power supply as the TCXO, what is the specific current draw spec for the VDDBAT pin only then? Why is it not in the datasheet?
I will be running the TCXO at 3.0 volts, can you tell me what the VDDBAT pin will reqiure for current?
Thanks,
