6.5.2
Twisted-Pair Receiver Interface
Figure 6-2 shows the design for the ICS1893 twisted-pair receiver interface.
Two 56.2
1% resistors are in series, with the center bypassed to ground with a 0.1-F bypass
capacitor.
No bypass capacitor is used with the receive transformer center tap.
A 4.7-pF capacitor must be included across the ICS1893 side of the receive transformer.
Note:
1.
Keep leads as short as possible.
2.
Install the resistor network as close to the ICS1893 as possible.
