`
`FM OPERATOR TYPE-LII (OPLII)
`
`•OUTLINE:
`The OPLII(FM OPERATOR type-LII) is an LSI IC which can be used as a sound generation
`system for computer apparatus, teletext instruments, etc. The OPLII employs frequency mod(cid:173)
`ulation for the melody sounds, and has rhythm sounds very close to those of natural musical
`instruments, making it possible to synthesize various tones by software control from a CPU.
`In addition, an LFO is built in to generate effects such as vibrato and tremolo, thus reducing
`the software load.
`The OPLII can be easily interfaced with the DAC YM3014.
`
`•FEATURES
`• FM sound generation system for realistic sound
`• Mode selection of simultaneous voicing of 9 sounds or 6 melody sounds and 5 rhythm sounds
`is possible. Both modes can produce various sounds.
`• Built-in vibrato oscillator/amplitude modulation oscillator (AM)
`• Composite sine wave speech synthesis also possible
`• Inputjoutput TTL compatible
`• Si-gate CMOS-LSI
`• 5V single power supply

`
`iENERAL FUNCTIONS
`OPLII has two voice modes: simultaneous voicing of 9 sounds, and 6 melody sounds and 5
`rhythm sounds. Furthermore, these melody sounds can be produced with different voices at
`one time. Operation by software control makes the OPLII suitable as a sound generation system
`for computer-based apparatus such as game machines, teletext, etc.
`The frequency modulation system in the OPLII synthesizes tones with 2 operators in 9 channels.
`The resultant algorithms are expressed by the following formula.
`Ft = It sin w1t + l2 sin w2t -(1)
`F2 = h (w1t + l2 sin w2t) -(2)
`where formula (1) shows the production of a tone by sine waves addition,and formula (2) shows
`a sine wave modulating another sine wave, i.e. frequency modulation.
`The synthesizer, which mixes several waveforms, and the noise generator are used to produce
`each individual rhythm sound. Five voices are available: Bass drum (BD), Snare drum (SD),
`High hat (HH), Top cymbal (TC), and Tom (TOM).
`The following 8 functional blocks detail the OPLII internal configuration.
`1. Register array:
`Voice parameters and data for FM operation such as frequency data are set here. All the
`functions of the OPLII are controlled by the data set in this register array.
`2. Phase generator:
`This circuit generates the frequency of the operators (phase) data, which corresponds to
`the frequency data set in the register array, to determine the frequency of the operators.
`3. Envelope generator:
`This is a circuit which creates the envelope, that is the change in the sound over time that
`corresponding to the register data.
`4. Operator:
`The operator receives the phase data (wt) from the phasegenerator and the envelope data
`(l(t)) from the envelope generator, and computes I sin wt.
`5. Accumulator:
`This accumulates the output levels of the operators at each sampling period (sampling
`is carried out at 50kHz), and converts them into data available for the DAC and interface.
`6. Vibrato/Amplitude modulation oscillator:
`This is a low frequency oscillator for vibrato and amplitude modulation.
`7. Timer:
`General purpose timer applicable for variable length time settings.
`8. Data bus controller.
