GPIO/ LED The GPIO and LED lines allow buttons and LEDs to be connected to the AVMD6600SWA91 to allow the user to control the Audio Magic system and communicate the system’s state to the user. Analog Audio These pins form the AVMD6600-SWA91RXA module’s analog audio output. The analog ground on the module and should be isolated from the host system’s ground to prevent the creation of noise-inducing ground loops. RESET_N This pin connects directly to the “RESET_N” pin on the AV6600 IC and is used to signal the module to power on and off. V3.3 This pin provides power to all elements of the AVMD6600-SWA91. Internal regulators condition the input power according to the requirements of the various sub-circuit blocks. I2S These input pins connect to the AV6600’s digital audio interface and provide a digital audio input channel. The AVMD6600-SWA91 TXD is always an I2S slave while the AVMD6600-SWA91 RXD can be either a Slave or a Master I2S port but the module cannot generate MCLK as an output.. Depending upon module configuration the audio data direction will change.

AMR corresponds to the maximum value that can be applied without leading to instantaneous or very short-term unrecoverable hard failure (destructive breakdown). Stresses beyond those listed under AMR may cause permanent damage to the device. Functional operation of the device at these or any other conditions beyond those indicated under “Recommended Operating Range” is not implied. Exposure to absolute-maximum-rated conditions for extended periods may adversely affect device reliability. Device functional operating limits and guaranteed performance specifications are given under Electrical Characteristics at the test conditions specified.
