HI,

I use the LMK04803 to generate clocks.

Mode: Single PLL, Internal VCO, 0-Delay

Input clock: 40Mhz；

Output clock:80MHz(11 channels)。

The parameter "PLL2_N_CAL" is different:

Hi,

During the VCO calibration in feedback path mode, PLL2_N_CAL doesn't affect or may be can keep same as PLL2_N value. Hence, while doing 0-delay mode, both values seems differ but can be set PLL2_N_CAl value same as PLL2_N settings.

Thanks!
