4.2.2 Receive Interface
Receive data is typically transformer coupled into the receive inputs on
TPIP/N and terminated with an external resistor as shown in
Figure 11
.
The transformer for the receiver is recommended to have a winding
ration of 1:1, as shown in
Figure 11
. The specifications for such a
transformer are shown in
Table 21
. Sources for the transformer are listed
in
Table 22
.
The receive input needs to be terminated with the correct termination
impedance to meet the input impedance and return loss requirements of
IEEE 802.3. In addition, the receive TP inputs need to be attenuated. It
is recommended that both the termination and attenuation be
accomplished by placing four external resistors in series across the
TPIP/N inputs as shown in
Figure 11
. The resistors should be
25%/25%/25%/25% of the total series resistance, and the total series
resistance should be equal to the characteristic impedance of the cable
(100 ohms for UTP, 150 Ohms for STP). For 100 Ohm twisted pair, the
resistor string values should be 25 Ohms each (1%). It is also
recommended that a 0.1uF capacitor be placed between the center of
