If you are referring to the 180 phase shift here is an example where
analog switch was used to select either input signal or its 180 phase
difference -

Here is another example, attached.
Note, an open drain output could act as the switch.

@makhan,
Attached is a DDS24 component with dual variable phase output and a demo project (sweep generator). DDS24 component was written for use in Lock-in detector project. For variable phase project demo see my older post
Project based on custom DDS24 component, written in Verilog for PSoC5LP (it will not fit PSoC4). DDS24 component library is included. To add component to this project in Creator go to Project->Dependencies->User dependencies and add DDS24.cyprj file. For best accuracy use quartz stabilized clock. Without XTAL frequency noise is about 1E-3, with XTAL accuracy is about ~1E-6.

makhan,
this forum is dedicated to community components. Please do not post general questions about PSoC5 programming here, use instead PSoC5 device programming thread. If you move there, in reward I will give you a lock-in demo also.
