5.5.1 Twisted-Pair Transmitter Interface
ICS1893Y-10 Rev F 1/20/04
The twisted-pair transmitter driver uses an H-bridge configuration, which requires that the transmit
transformer not have a choke on the chip side. ICS suggests any of the following for the H-bridge:
•
•
•
Figure 5-1
•
•
•
Note:
1. If the transmit transformer has a choke, put a choke on the RJ-45 side. Do not put a choke on the
2. Keep all TX traces as short as possible.
3. When making board traces, 50 Ω -characteristic impedance is desirable
4. Include a 0 Ω resistor in series with TP_CT. (Some systems work better without the TP_CT connection.)

Two 61.9 Ω 1% resistors are in series, with a 120-nH 5% inductor between them. These components
form a network that connects across both the transformer and the ICS1893Y-10 TP_TXP and TP_TXN
pins.
The ICS1893Y-10 supplies the power to the transformer. (No VDD connection is required.)
The ICS1893Y-10 TP_CT pin is connected directly to the transformer transmit center tap connection and
is bypassed to ground with a 100-pF capacitor. The transformer center tap must not connect to the
resistor/inductor network.
