SSI2130 VCO Evaluation PCB

SSI2130 VCO Evaluation PCB

The SSI2130 offers unprecedented performance and features, but its ultra-compact QFN package can present prototyping challenges. The EVB2130 eases evaluation by providing a PCB that allows comprehensive exploration of capabilities. Two versions are available: the EVB2130-B blank board with only a SSI2130 attached, and the EVB2130-P which is fully populated and ready for the bench. With exception of the SSI2130, all components are through-hole for easy construction and experimentation.

A on-board +5V regulator and 2.5V reference simplify external power connections, and pots are provided for mixer control, PWM, and VCO setup. Switches ease selection of saw ramp direction plus Through-Zero and Pulse Modulation. The schematic, bill of materials, and a user guide follow; refer to the SSI2130 data sheet for detailed information on use of the IC.
