My place to store and improve KiCad boards and schematics

This board essentially consists of a PCM5102A DAC and TPA6132A2 amplifier ICs.

PCM5102A IC is used in PLL operation schematic. It means SCK pin is not used and frequency generation happens internally, using phase-locked loop control system. According to the datasheed, this configuration is not in any way bad and even slightly reduces electromagnetic interference. I am using PCM5102A because it has high sound quality and mute circuitry. Also, I ordered a board with this chip to test with Raspberry Pi before starting my own one.
