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.

Warm Up Time
Frequency versus Vc Over Temperature
Figure 1
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.

Figure 5
Figure 5 shows an output frequency change of 125ppb typical over 85
days at 85°C which would be equivalent to 125ppb over 2.25 years at
40°C.

Figure 11
Figure 11 is a phase noise plot at a 2.8, 3.0, 3.3 and 3.6 volt power supply
which demonstrates there is no significant change in performance.
