VS-750 Dual Frequency VCSO
The VS-750 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." It also has an output disable to facilitate on-board testing.
