Figure 5-2. ICS1893Y-10 Receiver Twisted Pair
ICS1893Y-
Two 56.2 Ω 1% resistors are in series, with the center bypassed to ground with a 0.1- µ F bypass
capacitor.
No bypass capacitor is used with the receive transformer center tap.
A 4.7-pF capacitor must be included across the ICS1893Y-10 side of the receive transformer.
