I would like to connect the SI5394 to an I2C link. In that case the I2C_SEL pin should be tied to 1.
- If this pin left unconnected, is I2C_SEL level = 1 ? (internally pull - up 20K)
- or should I connect it directly to VDD or wiht external pull up resistor ?
Thanks for your help.
Since I2C_SEL pin is internally pull up, it is not necessary to add an external pull-up resistor to I2C_SEL pin for your I2C link case.
If any further question, feel free to let me know.
