Question:
What is the recommended location of the TX AC coupling capacitors?
Answer:
Referring to the layout of the MAX4986 evkit, the input caps should be placed close to the host and the output caps should be placed close to the device. For example, if Quadrax connector goes to the host and SATA connector connects to the device, the input caps should be placed close to the quadrax and the output caps should be placed close to SATA.
