Abstract
There is disclosed in one example an integrated circuit, including: a network protocol circuit to provide communication via a network protocol; a network communication terminal having a configurable impedance; and a control circuit including a control input port, and circuitry to adjust the impedance of the network communication terminal responsive to an input signal.
Claims25
An integrated circuit, comprising:
- a network protocol circuit to provide communication via a network protocol;
- a network communication terminal having a configurable impedance;
- and
- a control circuit comprising a control input port, and circuitry to adjust the impedance of the network communication terminal responsive to an input signal.
1 more element
A network interface device, comprising:
- a serializer-deserializer (SERDES) configured to provide communication via a network protocol;
- a network physical layer (PHY) comprising a communication terminal having a variable impedance element;
- and
- an impedance controller comprising a control input and logic to adjust the impedance of the network communication terminal responsive to an input.
1 more element
A network management entity comprising:
- a processor;
- and
- one or more computer-readable mediums having stored thereon instructions to instruct the processor to:
- determine that a first link partner and a second link partner on an interconnect have poorly matched transmit or receive impedances;
- and
- instruct at least one of the link partners to adjust its transmit or receive impedance to improve communication.
