2.2.1
BIDIRECTIONAL LINK IN SMPTE
APPLICATIONS
When using the bidirectional link with power supply
transmission, the components (FB1, L1 and L2) and
layout are very critical. Changes in the design or
components may result in decreased performance.
2.2.2 PCB LAYOUT
All components in the high-speed signal path should be
0402 size for minimal parasitic effects.
Figure 2-4 shows a recommended layout for the
EQCO30R5 with uplink and power over coax.
