Notes:
* All the specifications for frequencies above 20 MHz are very preliminary
1. Aging rates are proportional to the operating frequency. Pull range will be adjusted accordingly to provide for lifetime
possibility to set on frequency
2. Close to the carrier phase noise deteriorates with increase in frequency.
3. Power consumption listed in the table is for 10.000 MHz, Sine-wave output, 0.5” height unit. With increase in upper
operating temperature, the power consumption will increase about 40 mW per 5ºC. CMOS output option will decrease
consumption by about 25 mW. 0.4” units will have about 5% more power consumption.
4. If Vref is not used for adjusting the frequency, Vc range can be increased to 5.0 V with either Vcc option.
5. The Vc input may or may not be internally biased to roughly Vref/2. If internal bias is needed – it has to be specified on
PO.
6. All parameters, unless otherwise specified, are at nominal conditions, ie: T=25°C, Nominal Vcc & Nominal Load.
7. Pin #2 Vref is optional, please see part number creation.
