TLK2711-SP: VDDA pins Current consumption

Swastik Saini

Part Number: TLK2711-SP

Hi,

I wanted to finalize VDDA supply filtering ferrite bead specifications, regarding this I have few queries-

What should be its impedance ( at 100 MHz)? EVM is having 600 Ohm whereas in Datasheet Figure 7-1 , 5 Ohm Ferrite bead is mentioned.
What is the current consumption of VDDA pins, it is required to finalize ferrite bead current rating.

Best Regards,

Hi Swastik:

Where did you see 600 ohm ferrite bead in EVM file?

Max current is 208mA for VDD.

Hi Brian

Please find BOM and schematics snippet.

Is 208mA max current is of VDDA pins or of combined VDD and VDDA pins?

Best Regards,

Hi Swastik:

600 ohm at 100Mhz should be fine, it can support 500mA.
