Comparator Bus

Last Updated: March 22, 2011

What is the use of comparator bus in the analog blocks of PSoC?


Comparator bus can be used as an interface between the analog and digital blocks.  The Comparator Buses are available as both Enable and Clock inputs to the digital blocks.  For example, the output of a Comparator placed in a CT block can be used to drive the Enable Input of a PWM placed in a digital block.  The comparator bus is used in user modules like ADCs, capsense CSD etc.  Apart from this, using the LUT on the comparator bus, 16 types of logical functions may be performed on adjacent comparator buses.
