b). Electrical Stabilization
Apart from mechanical compensation electrical stabilization is also required which can be achieved by taking following point into consideration while designing PLL system.
Decoupling: Use capacitors on supply voltage and charge pump supply lines because these are most vulnerable to noisy signals, Use of tantalum capacitors of 10uF, 1uF, 0.1uF, 100pF and 1kpF at the supply to the reference source.
