LP5521: 32kHz clock capacitive load

Nagendran Raja

Part Number: LP5521

Hi

I am using LP5521 in my design with external 32kHz clock to synchronize multiple LED drivers. Could you please let me know what is the capacitive load offered by CLK_32K pin?

I need this info to choose an oscillator of sufficient drive strength.

Thanks

Nagendra

    Hi Nagendra,

    We do not have a data of the capacitive load from CLK_32K pin. Normal GPIO could drive above 4 pcs LP5521 according to our application experience. Since 32k is not a fast speed, I think there is no special requirement for oscillator.
