VS-401
Description
The VS-401 VCSO (Voltage Controlled Saw Oscillator) from Vectron is a high frequency, ultra low phase noise oscillator designed
to support high speed data converters and 100G coherent optical receivers. The VS-401 provides 12fs rms jitter in the 12kHz to
20MHz integration bandwidth and is available from 1.3GHz to 2.5GHz.
