MSC now offers the new VS-401 VCSO (Voltage Controlled Saw Oscillator) from Vectron International. A key feature of the VS-401 is an ultra-low 12 femtoseconds (fsec) root mean square (rms) jitter over the entire bandwidth from 12 kHz to 20 MHz. The VS-401, provided in a 13 mm × 20 mm RoHS-conform SMD package, is designed for output frequencies from 1.3 GHz to 2.1 GHz. The device operates at 5 V supply voltage and provides in the temperature range from -20°C to +85°C a single-ended sinewave output of 5 dBm. Analog-to-digital converter (ADC) signal to noise ratio (SNR) is constrained by the broadband jitter of the reference clock, and this constraint grows as frequency of the input signal increases. Since the VS-401 provides less than 12 fsec broadband jitter, this allows high performance data converters to meet their full potential in terms of SNR and effective number of bits (ENOB), freeing up performance benefits that designers can take advantage of downstream in their architecture.
