TLK10232: Power Supply advices for TLK10232

Part Number: TLK10232

Is there any application note about power supply connections advices? (filter, tied together the supply inputs with same voltage). We want to simplify the power supply design, in order to save costs.

I recommend looking at the TLK10232 EVM users guide as a starting point for this. Section 4 and the first three pages of the schematic should be helpful. This is our recommendation on how to setup power supply connections for TLK10232.

Thank you, Malik

There are 6 linear regulators in the EVB to power supply the TLK10232, 4 of them are used for 1.0V. In order to simplify the power supply (using other regulators with more current ouput and the adecuade LC filters), is it possible tied together the next supply inputs? :

- VDDA_LS/HS and VDDT_LS/HS (1.0V analog power supply, with a LC filter for VDDA and other LC filter for VDDT).

- VDDD and DVDD (1.0V digital power supply, with a LC filter for VDDD and other LC filter for DVDD).

best regards,

It is possible to do this however this power supply would need to be able to provide enough current to support each power rail together.
