This datasheet seems to be new.
You can adjust with CD 1 kHz -60dB.
Bit 1 is most important.
You can listen with headphones and adjust so that the sine sounds as clean and pure as possible.
In the datasheet it looks like always the corresponding bit switch must be closed for calibration.
When all bits are adjusted, close all bit switches.
I don't know if those switches are necessary, maybe it is easier to adjust.
Equipment would be a spectrum analyzer, stand alone or PC+soundcard+software.

Since the pcm64 is based on the dac729, you can also consult the datasheet of dac729 for reference.
