7.3 Power Supply Recommendations

The LMH34400 operates on a single 3.3-V power supply. A low power-supply source impedance must be maintained across frequency; therefore, use multiple bypass capacitors in parallel. Place the bypass capacitors as close as possible to the supply pin, and place the smallest capacitor on the same side of the PCB as the LMH34400. Preferably, also place the larger-valued bypass capacitors on the same side of the PCB. However, the capacitors can be positioned on the opposite side of the PCB using multiple vias if layout space is overly constrained.
