Overview (continued)

8.1.9 Channel-to-Channel Crosstalk

Channel-to-channel crosstalk is defined as the voltage at the source pin (Sx) of an off-channel, when a 1-VRMS

signal is applied at the source pin (Sx) of an on-channel. Figure 25 shows the setup used to measure, and

Equation 3 is the equation used to compute, channel-to-channel crosstalk.

8.1.10 Bandwidth

Bandwidth is defined as the range of frequencies that are attenuated by < 3 dB when the input is applied to the

source pin (Sx) of an on-channel, and the output is measured at the drain pin (D) of the TMUX6104. Figure 26

shows the setup used to measure bandwidth of the mux. Use Equation 4 to compute the attenuation.
