Twisted-Pair Receiver Interface

The figure below shows the design for the ICS1893 twisted-pair receiver interface.

•

Two 56.2

Ω 1% resistors are in series, with the center bypassed to ground with a 0.1µF 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.
