functional description (continued)
de-emphasis filter
For audio sources that have been preemphasized, a precision 50
μ
s/15
μ
s de-emphasis filter is provided to
support the sampling rates of 44.1 kHz and 48 kHz. Pins DEM_SEL and DEM_EN select the de-emphasis
functions. See Figure 6 for a graph showing the de-emphasis filtering characteristics. See Table 3 for
de-emphasis selection.

de-emphasis selection
De-emphasis selection is accomplished by using the DEM_SEL and DEM_EN pins. See Table 3 for
de-emphasis selection description.

Disallowed state. Do not use.
error status reporting (VALID_L and VALID_R)
The following is a list of the error conditions that will cause the VALID_L and VALID_R pins to be asserted low.
–
No clocks
–
Clock phase errors
When either of the above conditions is met, the VALID_L and VALID_R goes low and the PWM outputs go to
the hard mute state. If the error condition is removed, the TAS5015 is reinitialized and the VALID_L and VALID_R
pins are asserted high.
serial interface formats
The TAS5015 is compatible with eight different serial interfaces. Available interface options are IIS, right
justified, left justified, and DSP frame. Table 4 indicates how these options are selected using the MOD0, MOD1,
and MOD2 pins.
