rxHYB AND rxLINE INPUT ANTI-ALIASING FILTERS  
rxHYB AND rxLINE INPUT BIAS VOLTAGE  
The –3dB frequency of the input anti-aliasing filter for the  
rxLINE and rxHYB differential inputs should be about  
1MHz. Suggested values for the filter are 750for each of  
the two input resistors and 100pF for the capacitor. Together  
the two 750resistors and the 100pF capacitor result in  
–3dB frequency of just over 1MHz. The 750input resis-  
tors will result in a minimal voltage divider loss with the  
input impedance of the AFE1103.  
The transmitter output on the txLINE pins is centered at  
midscale, 2.5V. But, the rxLINE input signal is centered at  
1.5V in the circuit shown in Figure 2 above.  
Inside the AFE1103, the rxHYB and rxLINE signals are  
subtracted as described in the paragraph on echo cancella-  
tion above. This means that the rxHYB inputs need to be  
centered at 1.5V just as the rxLINE signal is centered at  
1.5V. REFN (Pin 36) is a 1.5V voltage source. The external  
compromise hybrid must be designed so that the signal into  
the rxHYB inputs is centered at 1.5V.  
This circuit applies at both T1 and E1 rates. For slower rates,  
the antialiasing filters will give best performance with their  
–3dB frequency approximately equal to the bit rate. For  
example, a –3dB frequency of 500kHz should be used for a  
single pair bit rate of 500kbps.
