VS-501
Voltage Controlled SAW Oscillator
VS-501
Description
The VS-501 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-501 provides 12fs rms jitter in a 12kHz to
20MHz integration bandwidth and is available from 1.3GHz to 1.8GHz.
