Impedance adaptation process and device for a transmitter and/or receiver, integrated circuit and transmission system

An integrated circuit (IC) includes a device (10) that adapts the impedance to the characteristic impedance (Zc) of transmission lines (13) each connecting a transmitter (11) to a receiver (12). Two adaptation blocks (14, 15) reproduce the respective structures of the transmitters (11) and receivers...

Zusammenfassung:An integrated circuit (IC) includes a device (10) that adapts the impedance to the characteristic impedance (Zc) of transmission lines (13) each connecting a transmitter (11) to a receiver (12). Two adaptation blocks (14, 15) reproduce the respective structures of the transmitters (11) and receivers (12) and their impedance is adapted by a reference resistor (Rr). A closed loop control device (Len, Lep, Lrn, Lrp) reproduces the adaptation conditions in the transmitters (11) and receivers (12) respectively.
