1.Does HD3SS3212 chip support SGMII, HSGMII, USXGMII, if so, what is the form of these three interfaces? For example, is the difference line only connected with 0.1uF capacitor?
2. Supply status of the chip?
3. According to the chip data, the interface of the chip is a two-way switch, so it is only in the state of on and off. Is it ok for me to confirm the signal directions at both ends of the switch?
