Part Number: TS3DDR4000

Tool/software:

1、咨询下TS3DDR4000是否可以用于1Gbps的RGMII的MUX，此时物理时钟125MHz；

2、如果可以使用，TS3DDR4000的工作电压VDD=3.3V，RGMII电平是1.8V，也可以正常工作？

1. Can TS3DDR4000 be used for MUX of 1Gbps RGMII with a physical clock of 125MHz?

2. The VDD of TS3DDR4000 is 3.3V, and the RGMII IO voltage is 1.8V, can it also work normally?

Hello Liu,

1.This device will work properly in your system. I am assuming the actual signal being passed through the mux is 125MHz. In any case that frequency is fine for this device. Please check out this FAQ that talks more about multiplexer bandwidth.

2.Also this device can pass signals from 0V to 3.3V with a 3.3V supply. So 1.8V is fine!

Please let me know if you have any additional questions!

Regards,

Kameron
