My customer is using multiple DAC38RF83 on board operating with their internal PLL.
We’re trying to understand how we can cut the PLL auto tune time to the minimum ?
- If we know the device temperature , can we preset the LFVOLT ?
- If the temperature moved would the PLL stay locked or should we change the LFVOLT value ?
- Do we need to go through the auto-tune process for each DAC every time we auto-calibrate ?
Do we have any app-note on this topic or can we get a more comprehensive guidance ?
