Fully programmable cellular audio and video matrixes
D. Chaussy, R. Fox, J.-L. Jaffard · IEEE Transactions on Consumer Electronics · 1993
Two fully programmable audio and video matrixes designed in BiCMOS technology have been developed. Their flexibility, performance, and low cost allow them to satisfy the many and varied configurations of TV and VCR manufacturers' designs. These devices allow parallel connection of up to four devices and achieve the flexibility design goal while providing good noise, distortion, and crosstalk levels.>
