LMK04828: lmk04828 lock

David Siksik

Part Number: LMK04828

Hello,

I would like to use the the "STATUS LD1" pin in the LMK04828 as lock status in order to know that the device is after configuration and the output clocks are locked.

I didn't find the way to define it in the TICS sofware.

Can you please help with this issue?

Thank you,

David.

Hi David,

Are you using LMK04828EVM or custom board with LMK04828 for testing?

LMK04828EVM has an LED for STATUS_LD1 and STATUS_LD2 for lock detect status.

STATUS_LD1 can be configure for PLL1 and / or PLL2 lock status and can be set as per Table 63 in datasheet.

For PLL1 only lock status set 0x15F - 0B and follow the table for other settings.

Thanks!

Regards,
