The nominal voltage supply is 3.3 V; however, the TRF37x32 offers very consistent performance across the entire recommended voltage range. Signal isolation depends partly on power supply isolation. All supplies may be generated from a common source but should be isolated through decoupling capacitors placed close to the device. The typical application schematic in Figure 76 is an excellent example. Select capacitors with self-resonant frequency near the application frequency or noise frequency. When multiple capacitors are used in parallel to create a broadband decoupling network, place the capacitor with the higher self-resonant frequency closer to the device.
