    摘要: A method is provided to determine transmitter equalization coefficients and a number of transmitter equalization taps. The method may include transmitting a first signal pattern at a first frequency across a channel to a receiver and determining a first eye height of the received clock signal pattern at the receiver. The method may also include transmitting a second signal pattern at a second frequency across the channel to the receiver and determining a second eye height of the received clock signal pattern at the receiver. Transmitter equalization coefficients may then be determined based on the determined first eye height and the determined second eye height.

    摘要: To allow for reference current settings per multi-bit link (or alternatively, per apparatus), approaches for implementing closed-loop Tx swing control based on monitoring of a dummy circuit is provided herein. In accordance with some embodiments, provided is a dummy bit-link circuit to model operable bit-links in a multi-bit link, where each bit link has a transmitter with an adjustable swing level. Also provided is a reference generator circuit to control the transmitter swing levels based on test data driven through the dummy bit-link.
