DP83867IR: RGMII Timing spec Tr and Tf

Yusuke Mukuno

Part Number: DP83867IR

Regarding RGMII Timing spec Tr and Tf

Is this a characteristic that applies only to the clock (GTX, RXC)?
Or is it a characteristic that applies to all of TX_CTL, TXD, RX_CTL, RXD?

Thanks

Hi Yusuke,

The RGMII spec does not specify that Tr and Tf are only for the clock.

It is assumed that Tr and Tf are signal rise and signal fall time, respectively. So these 2 parameters are also applicable to TX_CTL, TXD, RX_CTL, RXD at the source of signal.
