The Model 335 from CTS is a voltage controlled crystal oscillator(VCXO) that operates from 19.44 to 212.5 MHz. It has differential LVDS or LVPECL output waveforms and has a frequency stability of ±50 ppm (25 ppm is also available). Model 335 requires a supply voltage between 2.5 and 3 V. It is available in a compact ceramic package that measures 7 x 5 mm and is ideal for communication applications that require a tight frequency control.
