... Appendix B: PCB Layout Suggestion The HSDL-3208 is a shieldless part and hence does not contain a shield trace, unlike the other transceivers. The following PCB layout guide- lines should be followed to obtain a good PSRR and EM immunity, resulting in good electrical performance. Things to note: 1. The AGND pin should be connected to the ground plane ...
