5072

The 5072 series is 155.52 MHz VCXO IC. It incorporates a 155.52 MHz fundamental frequency oscillator circuit and a differential LVPECL output circuit on a single chip. The oscillator circuit features characteristics optimized for VCXO operation, and includes a varactor connection pin. The 5072 series can be configured with few external components, making them ideal as miniature VCXO modules.
