Product Center
VitraSemi offers two product lines: modems and vocoders, available as ICs or modules to support needs ranging from chip-level development to module-level integration.
Modem
ModemA family of modems based on Power Line Communication (PLC) technology, supporting multiple modulation schemes for smart grids, industrial control, and smart city applications. Available in two forms—chips (ICs) and modules—to meet diverse needs ranging from chip-level development to rapid module integration.
