8.1.9 Channel-to-Channel Crosstalk

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

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 of an on-channel, and the output is measured at the drain pin of the TMUX6119. Figure 10 shows the

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