Note the following characteristic of this protocol.
Serial data is sampled with the falling edge of SCLK.
PWM Outputs
The TAS5015 is designed to be used with a discrete back-end. The TAS5015 PWM outputs provide differential
3.3-V square-wave signals. During normal operation these outputs represent the input PCM audio in the
pulse-width modulation scheme. In the hard-mute state the P outputs (PWM_AP_L, PWM_BP_L, PWM_AP_R,
and PWM_BP_R) are held low and the M outputs (PWM_AM_L, PWM_BM_L, PWM_AM_R, and PWM_BM_R)
are held high. In the quiet-mute state the differential PWM outputs have a 50% duty cycle.

Stresses beyond those listed under “absolute maximum ratings” may cause permanent damage to the device. These are stress ratings only, and
functional operation of the device at these or any other conditions beyond those indicated under “recommended operating conditions” is not
implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
