VST510

      The VST510 is designed as crystal controlled oscillators of surface mount tri-state VCXO.
      Some important specifications have been concluded into several points as follow. The first one is about its frequency range which would be from 2MHz to 80MHz. The next one is about its frequency stability which would be +/- 25ppm. The next one is about its temperature range which would be from 0°C to +70°C. The next one is about its output waveform which would be CMOS/TTL squarewave. The next one is about its output voltage for high level which would be 4.50 minimum. The next one is about its output voltage for low level which would be 0.40 maximum. The next one is about its current for high level which would be -16mA. The next one is about its output current for low level which would be 16mA. The next one is about its output duty cycle which would be 45 / 55 maximum measured at 2.5Vdc. The next one is about its rise /fall time which would be 6nS maximum. The next one is about its jitter (RMS) which would be 5pS maximum. The next one is about its phase noise (typical) which would be -65dBc/Hz at 10Hz abd -130dBc/Hz at 10kHz. The next one is about its tri-state input control output E/D time which would be typ 100nS. The next one is about its tri-state input control enable (Vih) which would be minimum 2.2V and disable (Vil) would be 0.8V maximum. The next one is about its supply voltage which would be +5Vdc +/- 5%. The next one is about its supply current which would be max 60mA.
      There are also some frequency control specifications about it. Its control voltage range would be from 0.5Vdc to 4.5Vdc. Its slope would be positive. Its control voltage for center frequency would be 2.5Vdc +/- 0.5Vdc. Ans its monotonic linearity would be less than +/- 10%. The next one is about its input impedance which would be min 50K. Its modulation bandwidth would be min 15kHz. And so on. For more information please contact us.
