What is the proper way to connect multiple ethernet devices via MDIO bus?
I know that MDIO (similarly to I2C) is open drain, so I think that I need (just as in I2C) two 1-4, 7 kOhm pull-ups both for MDIO and MDC pins (Do I actually need a pull-up for MDC pin as long as it is a clock output?).
So, my question is the following: if I want to connect 8 devices, what is the proper choice for nominals (1 kOhm or 4.7 kOhm) and is it sufficient to have only one pull-up on the bus or do I need multiple pull-ups (for each IC)? Thanks.
