8.2.2 Detailed Design Procedure

8.2.2.1 Signal Range

The ESDS314 has 4 identical surge protection channels with each channel supporting a signal range of 0 to 3.6

V. The device will work well with any Ethernet PHY that drives the single ended voltage on the data line up to a

3.6 V.

8.2.2.2 Operating Frequency

The ESDS314 has a capacitance of 4.5 pF (typical) and can support the 125 MHz operation of Ethernet

1000Base-T application
