13. LINE INTERFACE UNIT (LIU)
The LIU in the DS26504 contains three sections: the receiver, which handles clock and data recovery; the
transmitter, which generates waveshapes and drives the network line; and the jitter attenuator. These three
sections are controlled by the line interface control registers (LIC1–LIC4), which are described below.
The DS26504 can switch among T1, J1, E1, and 6312kHz without changing any external circuits. A
different transformer is used for 64KCC networks. For a list of recommended transformer part numbers,
go to www.maxim-ic.com/support. Figure 13-1 shows a network connection using minimal components.
In this configuration the DS26504, using a fixed 120 external termination, can connect to T1, J1, E1,
64KCC, or 6312kHz. The receiver can adjust the 120 termination to 100, 110, or 75. The
transmitter can adjust its output impedance to provide high return loss characteristics for 75, 100,
110, and 120 lines. Other components may be added to this configuration to meet safety and network
protection requirements. This is covered in the Recommended Circuits section (Section 13.8).
