TLK110: Single and dual supply operation in case of VDD_IO 1.8V

Alari Rotka

Part Number: TLK110

Hello,

If I am using 1.8V to supply the VDD_IO, do I have to refer to the dual supply operation schematics and connect the 1.55V supply to the PFBIN1 and PFBIN or does the single supply voltage operation still apply connecting only the 3.3V to the AVDD?

Best regards,

Hi Alari,

VDDIO does not involve the PFBIN connection.
VDDIO can be 1.8V, 2.5V or 3.3V.

If you want to supply an external 1.55V supply, you can do this on the PFBIN pins.
You will still need to apply a 3.3V supply for AVD pin.

Kind regards,
Ross
