Abstract:
A method and apparatus for equalizing a reflection in a reflective high speed serial link. The method involves obtaining an amplitude and delay time of a compensating pulse that is transmitted in response to a pulse transmitted on the serial link. The apparatus comprises a programmable delay element and a driver stage configured to transmit a delayed and amplitude adjusted version of a pulse transmitted on the serial link. A method for equalizing a plurality of reflections in a reflective high speed serial link. The method involves obtaining an amplitude and delay time of a first compensating pulse and an amplitude and delay time of a second compensating pulse. The method further involves transmitting the first compensating and second compensating pulses in response to a pulse transmitted on the serial link.
