Dual Frequency VCSO
VS-751
Description
The VS-751 is a SAW based voltage controlled oscillator that operates at the fundamental frequencies of the internal SAW filters.
These SAW filters are high-Q quartz devices that enable the circuit to achieve low phase jitter performance over a wide operating
temperature range. The dual oscillator is housed in a hermetically sealed leadless surface mount package offered on tape and
reel. It has a frequency select function that enables either “Frequency 1” or “Frequency 2.”
