The Sound Semiconductor FatKeys™ SSI2131 is an entirely new voltage controlled oscillator subsystem for high performance musical instruments. Buffered outputs include triangle, sawtooth, and pulse with PWM control. Triangle and sawtooth waveforms are improved from prior generation VCO designs. Both hard and soft sync are supported.

Optional trims are provided for exponential scale and high frequency tracking that can be automated by CPU-calibrated systems. The SSI2130 requires minimal external components and is available in an easy-to-use SOIC-16 pin package.

The SSI2130 has the same high performance VCO core with more features including a 5-channel VCA mixer, open collector square wave output, an on-chip sine-wave generator, and through-zero FM/PM capability.

The datasheet provides a wealth of design information and sample circuits.
