Does it is possible to change the Teseo-LIV4F PPS output frequency to a stable (low jitter) frequency greater or equal to 10MHz ?

Hi Benjamin,

For LIV4F we can output a 1 PPS pulse. The pulse duration can be changed to 1 us but the the frequency is 1 Hz. To change the pulse duration you can modify CDB 301. The default value is 0.5.

However we have chipsets that can output a higher frequency clock. I will private message you to find out more details.
