The clock that is used as the time base is generated by connecting a
16.9344 or 33.8688 MHz oscillator element between these pins. The
OSC OFF command turns off both the VCO and crystal oscillators.
Double- or quad-speed playback can be specified by microprocessor
command.
Connect a 16.9344 MHz oscillator element between the X
IN
(pin 77) and X
OUT
(pin 78) pins for double-speed
systems. The playback speed can be set by the normal-speed playback and double-speed playback commands.
Connect a 33.8688 MHz oscillator element between the X
IN
(pin 77) and X
OUT
(pin 78) pins for quad-speed
systems. An XTAL32M command must be issued to intialize such systems. Then the playback speed can be set by
the double-speed playback and quad-speed playback commands.
Recommended crystal and ceramic oscillator elements
Since the conditions for the load capacitors Cinand Coutused varies with the printed circuit board, this circuit
must be tested on the printed circuit board actually used.
25. 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. In quad-speed mode, it outputs the 33.8688 MHz external crystal oscillator 33.8688 MHz signal.
The 4.2M pin supplies the LA9231M or LA9231M system clock, normally outputting a 4.2336 MHz signal. When the
oscillator is turned off both these pins will be fixed at either high or low.
