PRODUCTION DATA
TAS5827 supports up to 4 phases of selection for the multi-device application system. For example, when a system integrates 4 TAS5827 devices, the user can select phase 0/1/2/3 for each device by registering RAMP_PHASE_CTRL Register (Offset = 6Ah) [Reset = 00h] , which means there is a 45-degree phase shift between each device to minimize the EMI.
There are two methods for Multi-Device PWM phase synchronization. Phase Synchronization With I2S Clock In Startup Phase or Phase Synchronization With GPIO.
