Product description
The SSI2130 is a new-generation voltage controlled oscillator subsystem for high-performance electronic musical instruments.
A complete analog synthesizer voice can be constructed at low cost with one or more SSI2130's, a SSI2144 or SSI2140 Voltage Controlled Filter, and SSI2162/2164 VCA(s). Buffered outputs include triangle, sawtooth, pulse with PWM control, and open collector square wave. An on-chip five channel mixer with linear control VCA's sums triangle, saw, and pulse waveforms plus two independent auxiliary inputs into a single current output. A precision analog multiplier provides unprecedented temperature-compensation, and careful attention was paid to improvement of triangle and sawtooth waveforms compared to previous generation VCO IC's. Both soft and hard sync are provided. An accurate and temperature stable sine wave can be produced by the internal sine shaper circuit. Through-zero FM and PM can be achieved with an exernal comparator, op amp, and several discrete components. Optional trims are provided for expo scale and high frequency tracking that can be automated by CPU-calibrated systems.
The SSI2130 requires minimal external components and is available in a diminutive 4x4mm QFN package.
