AM Interference Avoidance
Digital amplifiers can degrade AM reception as a result of their RF emissions. Texas Instruments patented AM
interference avoidance circuit provides a flexible system solution for a wide variety of digital audio
architectures. During AM reception, the TAS5504 adjusts the radiated emissions to provide an emission clear
zone for the tuned AM frequency. The inputs to the TAS5504 for this operation are the tuned AM frequency,
the IF frequency, and the sample rate. The sample rate is automatically detected.
