Hi,

The PSoCLP CapSense component datasheet includes the following:


We understand the relationship between scan speed and resolution scan speed and resolution.

 

For example,

CapSense input clock : 24MHzScan Speed : Fast

Divides the component input clock by 2 = 12MHz

 

What does this frequency indicate?
Is it a digital circuit clock?

Is this clock is "Clock from UDB"?

Regards,

Hello MaMi_1205306

This clock frequency indicates the modulator clock frequency that is provided to the counter. The scan time of a widget is calculated as (2^N - 1)*mod_clk_frequency, where N is the resolution of the widget.

This is a digital clock and is derived from MASTER_CLK.

You can check the Clocks tab in design wide resources for more details on the clock source.

Thanks and regards
