... VCOM is a common voltage of the analog signal. In order to eliminate the effects of high frequency noise, a 0.22µF ceramic capacitor should be connected as near to the VCOM pin as possible. And all signals, especially clocks, should be kept away from the VCOM pin in order to avoid unwanted coupling into the AK5393. No load current may be drawn from the VCOM pin. ...
