Sound Semiconductor Unveils Next Generation SSI2130 Voltage Controlled Oscillator IC

Following the recent expansion of Sound Semiconductor's range of IC products with new single and dual VCA chips, the Sonora, California, -based company founded by Dan Parks, now announced a new audio-band Voltage Controlled Oscillator (VCO) integrated circuit. The first new electronic music VCO IC in decades, the FatKeys SSI2130 has been a long time in the making, and credit is due to the company's great chip designers, which seem determined to quickly build up Sound Semiconductor's portfolio.

Sound Semiconductor announced single and dual channel VCA additions to its product lineup, the ProCircuit SSI2161 and FatKeys SSI2162.The ICs are part of a family of affordable high-performance VCAs from the company, now offering a single, dual and quad versions. The SSI2164 offers four VCAs in a compact SOP package with lowest cost-per VCA, while the new SSI2162 is a versatile building block for high-performance audio applications, and the single-channel SSI2161 provides lowest noise.

Asahi Kasei Microdevices Corporation (AKM) launched the AK1574, a fractional-N PLL synthesizer with a Voltage Controlled Oscillator (VCO) for frequency modulation, able to replace variable capacitance diode configurations. Targeting professional, portable, radio transmission systems, the built-in VCO supports from 46.875 to 1682.5MHz, saves space, has low-phase noise, and low-power consumption. Uses include two-way radios in the VCO configuration with a variable capacitance diode and a winding coil, with support for diversity receivers.
