Thank you everyone.

Right now I want to know if a commercial WWVB receiver IC provides a
significantly better quality than a regular radio receiver circuit does. The
manufacturer that we design for will make tens of thousands boards.
Therefore every penny counts. If a regular radio receiver circuit is cheaper
and has comparable quality we will design from scratch without using a
receiver IC. Does anyone know?

Thanks,
Tony
