SPRUJG2 December 2024 AM62D-Q1
The AM62D Audio EVM will have audio analog-to-digital converters (ADC) manufacturer part number PCM6240QRTVRQ1 to interface with McASP2 of SoC. The PCM6240 has Analog supply of 3.3V and digital supply of 1.8V and VBAT_IN is used for enabling input fault diagnostics.
The PCM6240QRTVRQ1 configuration control is supported over the SoC_I2C0 instance. In PCM6240QRTVRQ1 I2C target address is set using ADDR1_MISO and ADDR0_SCLK pins. The I2C address for audio device (PCM6240) are 0x48 and 0x49. The Buffer enable manufacturer part number SN74LVC1G126DBVR for the serial data output is controlled by the CPLD1.
The ADC is connected to 2x stacked 3.5mm TRS Audio Jack connectors with manufacturer part number STX-4235 for 4x Stereo Audio Jack Mic/Line In.
Reset: The reset for the PCM6240 is connected to a circuit that ANDs the RESETSTATz from the AM62D SoC with the signal GPIO_PCM_RST from the I/O expander. A pull-up resistor is provided on PCM_RSTn to set the default active state.
