Is the lock temperature range fixed or does it shift each time the synthesizer is retuned?
The lock maintenance range is centered on the ambient temperature in which the retuning or self-tuning algorithm is carried out. For instance, the Si4133 has a 300C lock maintenance range. If the self-tuning algorithm is carried out at 25C, the Si4133 can maintain lock in the -50C to 550C temperature range. If the self-tuning algorithm is carried out at 550C on the other hand, the Si4133 can maintain lock in the in the 250C to 850C temperature range.
