11 Layout

11.1 Layout Guidelines

Keep the external capacitor traces short. This is more important on C1 and C2 nodes that have the fastest rise and fall times. For best ESD performance, make the impedance from TRS202 ground pin to the ground plane of the circuit board as low as possible. Use wide metal and multiple vias on both sides of ground pin.
