High Shock Discrete
Voltage Controlled SAW Oscillator
VS-701
VS-701
Description
The VS-701 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 / 400G coherent optical receivers. The VS-701 provides 13fs rms jitter in a 12kHz
to 20MHz integration bandwidth and is available from 0.6 to 3.0GHz.
