SGMII Transmit Data. 1.25 GBaud input -
Positive and Negative.
Input impedance on the S_IN± pins may be
programmed for 50 ohm or 75 ohm imped-
ance by setting register 26.6. The input
impedance default setting is determined by
the 75/50 OHM configuration pin.
SGMII 625 MHz Receive Clock.
For Serial Interface modes
(HWCFG_MODE[3:0] = 1x00) the S_CLK±
pins become Signal Detect± (SD±) inputs.
SGMII Receive Data. 1.25 GBaud output -
Positive and Negative.
Output impedance on the S_OUT± pins may
be programmed for 50 ohm or 75 ohm
impedance by setting register 26.5. Output
amplitude can be adjusted via register
26.2:0. The output impedance default setting
is determined by the 75/50 OHM configura-
tion pin.
