We offer this modification only as a manually wired custom made product. The
inquiries have not been sufficient so far to offer a separate "module". It's
nothing but a switch (to switch between internal and external Quadrature
VCO), some capacitors and two sockets for sine/cosine in. For details
please refer to the pdf document
