Abstract
A switchable termination resistance circuit for a transceiver physical layer interface. Example embodiments include a switchable termination resistance circuit for a transmission line transceiver, the switchable termination resistance circuit comprising: first and second terminals for connection to a transmission line; first and second NMOS termination resistance switches having source connections connected together at a midpoint node and gate connections connected to an input node; a first resistor connected between the first terminal and a drain connection of the first NMOS termination resistance switch; a second resistor connected between the second terminal and a drain connection of the second NMOS termination resistance switch; a Zener diode having a cathode side connected to the input node and an anode side connected to the midpoint node; and a branch comprising a second Zener diode, a branch diode, a branch NMOS switch and a branch PMOS switch in a series connected arrangement between the midpoint node and a ground line.
