The EN29A0QI was designed with low-noise performance in mind. With an integrated inductor, physically small internal current loops and integrated high-frequency filter capacitors, the EN29A0 is ideal for use in noise sensitive applications and is capable of meeting stringent radiated emissions requirements. Using the standard recommended layout that was presented earlier and with a 9A resistive load on the output, the EN29A0QI emissions spectrum falls at least 10dB below the CISPR 32 Class B 3 meter limits, even when operating at high conversions ratios as would be the case when converting from a 12V input voltage to the lower voltage rails for noise-sensitive transceivers in FPGAs and ASICs.
