double speed
Double-speed mode is used to support sampling rates of 88.2 kHz and 96 kHz. In order to put the TAS5010 in
double-speed mode with the device in normal operating conditions, the RESET pin must be held low while
switching the DBSPD pin high. After the RESET pin is brought high again, a reset sequence takes place. If the
change is at power up, a power-up sequence is originated.
quad speed
Quad-speed mode is used to support sampling rates of 176.4 kHz and 192 kHz. It is supported in slave mode
only. In order to put the TAS5010 in quad-speed mode, M_S and DBPSB pins are brought low. Quad-speed
mode is then automatically detected due to the fact that it is the only mode in which MCLK_IN is 128Fs.
de-emphasis filter
For audio sources that have been preemphasized, a precision 50
s/15 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.
