RECEIVER EQUALIZATION CIRCUITRY USING VARIABLE TERMINATION AND T-COIL
Systems, apparatuses, and methods for performing efficient data transfer in a computing system are disclosed. A computing system includes multiple transmitters sending singled-ended data signals to multiple receivers. In order to better handle noise issues when using single-ended signaling, one or more of the receivers include equalization circuitry and termination circuitry. The termination circuitry prevents reflection on a corresponding transmission line ending at a corresponding receiver. The equalization circuitry uses a bridged T-coil circuit to provide continuous time linear equalization (CTLE) with no feedback loop. The equalization circuitry performs equalization by providing a high-pass filter that offsets the low-pass characteristics of a corresponding transmission line. A comparator of the receiver receives the input signal and compares it to a reference voltage. The placement of the comparator and the ratio of the inductances of the inductors of the bridged T-coil circuit are based on whether the receiver includes self-diagnostic circuitry.
Network transformer module
A network transformer module includes a first magnetic element and a second magnetic element. The first magnetic element includes a first iron core and a first coil winding. The first coil winding is composed of a first wire and a second wire, and is wrapped 7 to 14 turns around the first iron core. The second magnetic element includes a second iron core and a second coil winding. The second coil winding is composed of a third wire and a fourth wire, and is wrapped 2 to 5 turns around the second iron core.
