EQCO850SC.3-HS/EQCO875SC.3-HS
3.1 Guidelines for PCB Layout
Because signals are strongly attenuated by long cables,
special attention should be paid to the PCB layout
between the coaxial connector and the EQCO850SC-HS.
The EQCO850SC-HS should be as close as is practical
to the coaxial connector. The trace between the coaxial
connector and the EQCO850SC-HS (EQCO875SC-HS)
must be a 50Ω (75Ω) trace referenced to GND. To avoid
noise pickup, other traces carrying digital signals or fast-
switching signals should be placed as far away as
possible from this trace.
The following diagram shows the layout of the critical
section of the PCB, from the coax connector to the twin
differential input pairs:
