24. CONT pin; Pin 73: CONT
The CONT pin goes high when a CONT SET command is issued.
The clock that is used as the time base is generated by connecting a 16.9344 MHz oscillator element between these
pins. The OSC OFF command turns off both the VCO and crystal oscillators. Double-speed playback can be
specified by microprocessor command.
Connect a 16.9344 MHz oscillator element between the XIN (pin 77) and XOUT (pin 78) pins for double-speed
systems. The playback speed can be set by the normal-speed playback and double-speed playback commands.
Recommended crystal and ceramic oscillator elements
Since the conditions for the load capacitors Cin and Cout used vary with the printed circuit board, this circuit must be
tested on the printed circuit board actually used.
26. 16M and 4.2M pins; Pin 71: 16M, pin 72: 4.2M
In normal- and double-speed playback modes, the 16M pin buffer outputs the 16.9344 MHz external crystal oscillator
16.9344 MHz signal. The 4.2M pin supplies an LA9230/40 Series LSI system clock, continuously outputting a
4.2336 MHz signal. When the oscillator is turned off both these pins will be fixed at either high or low.
