27. Clock oscillator; Pin 53: XIN, pin 52: XOUT
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.
Use a 16.9344 MHz oscillator element if the application circuit implements a 2
×-speed playback system. The
system control microprocessor can then issue 2
×-speed or normal-speed playback commands.
Use a 33.8688 MHz oscillator element if the application circuit implements a 4
×-speed playback system. When
implementing a 4
×-speed playback system, use a 33.8688 MHz oscillator element and send a XTAL32M command
($CF) at system initialization. After initialization, use the 4
×, 2×, and normal-speed playback commands to set the
playback speed.
28. 16M and 4.2M pins; Pin 75: 16M, pin 76: 4.2M
If a 16.9344 MHz oscillator element is used, the 16M pin will output a 16.9344 MHz signal from a buffer circuit in
2
×-speed and normal-speed playback modes. If a 33.8688 MHz oscillator element is used, the 16M pin will output a
33.8688 MHz signal from a buffer circuit in 4
×-speed playback mode. The 4.2M pin functions as the
LA9230/LA9240 Series system clocks and always outputs a 4.2336 MHz signal. In oscillator off mode, both of these
pins are held either high or low.
29. Reset circuit: Pin 72: RES
This pin must be pulled low temporarily and then set high after power is first applied. This sets the muting to –
∞ dB
and the disc motor to stopped.
Setting the RES pin low directly sets the states enclosed in boxes.
