2.12.4 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 TAS5508A adjusts the radiated emissions to provide an
emission-clear zone for the tuned AM frequency. The inputs to the TAS5508A for this operation are the
tuned AM frequency, the IF frequency, and the sample rate. The sample rate is automatically detected.
