Application Note for Miniature Pulse Transformers

2795T and 2795YTransformers Application Note  
The 2795T and 2795Y transformers provide two transformation ratios to match both 75and  
120line impedances with Lucent 3.3 V transceivers using a single terminating network design.  
These dual-ratio transformers can also be used for 100lines with a change in resistor values.  
The 2795T is optimized for the receive function, while the 2795Y is optimized for the transmit  
function.The 2795T can be used for both receive and transmit operation; the 2795Y is designed  
for transmit operation only. Suggested applications for a single-transformer design solution (two  
2795T transformers) are shown in Figure 1.The recommended two-transformer design solution  
(2795T and 2795Y) is shown in Figure 2. For 2795T and 2795Y data sheet refer to document  
TM00145.  
Single-Transformer Design and CommonTermination Network  
A typical line termination network using the 2795T transformer for both the receive interface  
and the transmit interface is shown below for a single channel.The termination network consists  
of capacitors and resistors arranged to provide the proper voltage gain and impedance matching  
to the characteristic impedance of the various transmission lines. The network is designed to  
operate with both E1 cable impedances (75and 120) with no change in components. For  
DS1 applications (100), only the resistor values need to be changed.The same transformer  
can be used for all three cable impedances in both receive and transmit operation. Figure 1  
below shows the proper connections for each cable impedance. Connections for cable selection  
are made on the line side for the receive interface and on the device side for the transmit interface.  
The components and suggested values are listed in Table 1. Capacitor CS provides high-frequency  
return loss enhancement.
