As the USBLC6-2 is designed to protect high speed data lines, it must ensure a good
transmission of operating signals. The frequency response (Figure
gives attenuation
information and shows that the USBLC6-2 is well suitable for data line transmission up to
480 Mbit/s while it works as a filter for undesirable signals like GSM (900 MHz) frequencies,
for instance.
