DS30EA101: Does it matter how close a capacitor or resistor is located to the BNC connector

Brittany Cohen

Part Number: DS30EA101

I am using the DS30EA101 and I wanted to know if it matters how close I put my capacitors, resistors, and inductors in relation to the BNC connector. Do these components need to be close to the BNC connector? Does it matter where they are located? and if so, why? 

This is my schematic 

This is my PCB layout 

Thank you!

    1). We should put passive return loss network as close to the device as possible.

    2). It would be best to have shortest distance between BNC connector and the device.

    3). Please rotate DS30EA101 90 degrees counter clock wise.

    4). Please attached note pcb layout of one of our devices similar to DS30EA101. Please follow the same layout - if possible. Pleas euse Allegro free viewer to open and read this file.
