Hi,
in the datasheet it says it's suitable for ethernet.
But most ethernet are just 10M or 100M.
Can it be used for 1000M?
A more general question is: how to tell if an ESD protection device would be suitable for a specific speed communication interface?
Hi,
Welcome to E2E!
The TPD4E1U06 is able to support 1000M Ethernet. In order to see how the capacitance of the device will affect the data signal you would need to consider the insertion loss of the device. A good rule of thumb is staying under 3dB insertion loss. Gbps divided by 2 will give the value in GHz. Using the GHz value and Figure 11 in the datasheet will allow us to see the amount of insertion loss from the device.
1000Mbps = 1Gbps = 0.5GHz
From the graph we can see that at 0.5GHz speed the insertion loss from the device is close to 0dB meaning the device will have little effect on signal integrity.
Best regards,
