DS64BR401 Configuration pins

Kikuo Mita

Please advise me.

There are several input pins which are sued to configure the devices such as DEMA0/1, EQA0/1 etc.
Some of the pins are bi-level and others are try-level input.

How much resister value do you recommend between pin and GND or Vcc, when you configure
these pins 0 or 1.

Mita-san,

The three-level pins should have a resistor to GND or VDD to configure as a 0 or 1. It is acceptable to tie them directly to GND or VDD, but this makes any changes more difficult to achieve. Using the resistors allows for changes with just an adjustment to the BOM. The recommendation for resistor value is 1K ohms.

Regards,

Lee
