Hello Champs,

 

I'd like to decide internal PUS, PUE and/or PKE and the values.

In the HDGW 9.5.1.2 RGMII discusses as follow.

 

“Drive strength Controlled by bits [5:3] (DSE) of the following registers

in IOMUXC (IOMUX controller):

IOMUXC_SW_PAD_CTL_PAD_RGMII_TXC

IOMUXC_SW_PAD_CTL_PAD_RGMII_TX_CTL

IOMUXC_SW_PAD_CTL_PAD_RGMII_TDx (4 registers)

IOMUXC_SW_PAD_CTL_PAD_RGMII_RXC

IOMUXC_SW_PAD_CTL_PAD_RGMII_RX_CTL

IOMUXC_SW_PAD_CTL_PAD_RGMII_RDx (4 registers)”

 

However the IBIS currently supports only the 2.5 V option.

We are using 1.5V.

 

Could you advice how to decide PUS, PUE and/or PKE and the values?

 

BR,
N.S.
