11.1 Layout Guidelines
Two key layout guidelines are:
1. TX1, TX2, and TX3 are fast-switching lines and must be routed away from sensitive lines (such as the INP,
INN inputs).
2. The device can draw high-switching currents from the TX_SUP pin. A decoupling capacitor must be
electrically close to the pin.
