... The performance of the internal low pass filter from DC to 24kHz is shown in Figure 12. The higher frequency rolloff of the filter is shown in Figure 13. If the user’s application has the PCM1712 driving a wideband amplifier recom- mended to use an external low pass filter. A simple 3rd- order filter is shown in Figure 14. For some applications, a passive RC filter or 2nd-order filter may be adequate ...

... This evaluation fixture is primarily intended for quick evalu- ation of the PCM1712’s performance. DEM-PCM1712 can accept either an external clock or a user-installed crystal oscillator. All of the functions can be controlled by on-board switches. DEM-PCM1712 does not contain a receiver chip or an external low pass filter. DEM-PCM1712 requires a single +5V power supply. 1 1500pF 4 ...
