LMX2594: definition of the lock time of the PLL for MASH_RST_COUNT

Noriyuki Takahashi

Part Number: LMX2594

Hi team

In the datasheet, MASH_RST_COUNT needs to be greater than the lock time of the PLL.

Could you tell the definition of the lock time of the PLL? I am not sure whether the time includes VCO calibration time and so on.

Regards,

Hi Takahashi-san,

The delay time is equal to (MASH_RST_COUNT x 2^CAL_CLK_DIV) / fosc.

Hi Takahashi-san,

Lock time is referring to the analog PLL lock time, which is approximately equal to 4 / loop bandwidth.
