16 Figure 7. Recommended ac coupling and data signal termination. NOTE: AC coupling capacitors should be used to connect data outputs to data inputs between the HFBR-772BWZ, HFBR-782BZ, and host board ICs (eg ASIC) with either 50 Ω single ended or 100 Ω differential terminations as shown. The capacitors' value can be reduced from 100 nF (0603 size) if the data rate and run length are limited.
