18. Digital output circuit; Pin 43: DOUT
This is an output pin for use with a digital audio interface. Data is output in the EIAJ format. This signal has been
processed by the interpolation and muting circuits. This pin has a built-in driver circuit and can directly drive a
transformer.

The clock that is used as the time base is generated by connecting a
16.9344 MHz crystal oscillator between these pins. The OSC OFF
command turns off both the VCO and crystal oscillators. Also, the
LC78681KE can be set up to handle double speed playback simply
by issuing a command. The table below lists the relationships
between the crystal and VCO oscillators.
