QuartzCom AG Quartz Oscillators - VC-TCXO - VC-TCXO SMD Type VTO-SK-S-4p

The VTO-SK-S-4p is a surface-mount device (SMD) voltage-controlled temperature-compensated crystal oscillator (VC-TCXO) designed for applications in telecom infrastructure, broadband access, and navigation. It operates within a frequency range of 10 to 400 MHz and provides a sine wave output signal. The device features low phase noise, with specifications of -142 dBc/Hz at a 50 MHz carrier frequency for 1 kHz offset and -150 dBc/Hz at 10 kHz offset. Frequency stability is rated at ±0.5 to ±5.0 ppm over temperature variations, with an additional stability of ±0.2 ppm against supply and load changes. The oscillator has a frequency tolerance of ±1.0 ppm at +25 °C and an aging specification of ±1.0 ppm for the first year. It can be powered by either 3.3 V or 5.0 V supply voltage, with a supply current ranging from 10 to 60 mA. The VTO-SK-S-4p supports a frequency pulling range of ±5 to ±15 ppm and has a voltage control input of +1.65 V ±1.35 V. The operating temperature range is suitable for commercial applications from -20 to +70 °C, with an industrial option available from -40 to +85 °C. The device is packaged in tape and reel for easy integration into manufacturing processes.
