CPC H04L 25/0298 (2013.01) [H04L 25/0278 (2013.01)] | 18 Claims |
1. A method for calibrating termination resistors for a communication link including a transmitter coupled to a receiver via a channel, the transmitter having an adjustable transmit termination resister (Rtx) and the receiver having an adjustable receiver termination resister (Rrx), the method comprising:
in conjunction with link training for the communication link,
using a first calibration process to calibrate a resistance value for the Rrx under which a resistance value of the Rrx is adjusted to obtain a maximum peak amplitude of a signal received at the receiver during transmission of a link training pattern.
