1. See Standard Frequencies and Ordering Information.
2. Parameters are tested with production test circuit (See data sheet on web).
3. Parameters are tested at ambient temperature with test limits guardbanded for specified operating temperature.
4. Measured as the maximum deviation from the best straight-line fit, per MIL-0-55310.
5. Measured from 20% to 80% of a full output swing.
6. Not tested in production, guaranteed by design, verified at qualification.
7. Integrated across 50 kHz to 80 MHz, per OC-192.

Description
The VS-550 is a dual output (selectable output) SAW based
voltage controlled oscillator that operates at the fundamen-
tal 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 her-
metically sealed J-lead surface mount package offered on
tape and reel. It has a frequency select to function that
enables either “Frequency 1” or “Frequency 2”.
