1. The Output is DC coupled.
2.
The VT-803 power supply pin should be filtered, eg, a 10uF, 0.1uF and 0.01uf capacitor.
3. Not all stabilities are available over all temperature ranges. Measured at mid Vc for parts with frequency tuning.
4. After 2 IR reflows and 24 hours.
5. ±100, ±200 and ±280 ppb temp stability parts, all inclusive with 10 years aging.
6. Output is Enabled if E/D is left open.

The VT-803 start up time is rated at 2ms. Figure 1 shows the Output
Frequency versus time in seconds which shows the output reaching a
steady state frequency within 60 seconds.
Figure 2
The VT-803 output frequency change versus control voltage is very linear
and Figure 2 show the typical performance over temperature.
