2.10.2 DAC Clock Noise

The system clock is visible as clock noise on the output of the DAC. Peak-to-peak noise is in the 0.7-1.6 mV at 2 MHz and 0.05-0.1 mV at 32 MHz range. If the external clock is used as a system clock, the noise is up to three times higher.

Work Around

Add an external low-pass filter to remove the noise.
