1.5 External Circuits
1.5.1 External Termination Resistors
There are no external termination resistors required. For both Upstream and Downstream the dedicated
50 Ohm termination resistors are integrated in the circuit.
1.5.2 External Coupling Capacitors
1.5.2.1 Downstream Coupling Capacitors
The serial data path in downstream direction requires coupling capacitors according Figure 1-17. Recommended value for all capacitors is 100nF (X7R) for all operation modi.
Figure 1-17: Downstream Coupling Capacitors
1.5.2.2 Upstream Coupling Capacitors
The serial data path in upstream direction requires coupling capacitors according Figure 1-18. Recommended
value for all capacitors is 100nF (X7R). Values depend on cable length and serial upstream data rate in combination with the selected APIX operation mode.
