Notes:
1* Higher frequencies can be achieved either by using higher frequency crystals or by low noise analog harmonic multiplication. Both
methods have advantages and drawbacks. If lowest possible phase noise on the noise floor is most important – high frequency crystal will be used. If
phase noise close to the carrier and aging are more important – multiplication will be used. Please consult factory for your specific requirement.
2* Aging rate is usually proportional to the operating frequency, unless higher frequency is achieved by multiplication. Keep it in mind
while specifying aging.
3* Phase noise deteriorates with frequencies going higher. If analog multiplication is used to achieve higher frequency the phase noise
roughly follows the formula of additional 20LogN, where N is a multiplication factor across entire frequency offset range. If higher frequency is
achieved by using higher frequency crystal phase noise close to the carrier deteriorates due to the lower Q of the crystal and is usually worse,
compared to multiplied solution. On the noise floor, however it remains more or less the same. This design usually starts utilizing multiplication
techniques in the range of 25 MHz to 35 MHz.
4* Pads “A” and “B” may or may not appear on the actual package. They can be used when additional functions i.e. “Oven Ready” alarm
or “Tristate” are specified. Please consult factory.
