Adaptive Transmit Equalizer
US Patent:
7450636, Nov 11, 2008
Filed:
Sep 5, 2002
Appl. No.:
10/235357
Inventors:
Patrick J. Lee - San Jose CA, US
William W. Brown - Los Altos CA, US
William W. Brown - Los Altos CA, US
Assignee:
Avago Technologies General IP (Singapore) Pte. Ltd. - Singapore
International Classification:
H03H 7/30
US Classification:
375232
Abstract:
An adaptive transmit equalizer for equalizing digital symbols to be transmitted over a communications channel includes a transmit filter having an associated register for storing at least one filter coefficient. A tuning engine generates performance metric values based on digital symbols received through the communications channel. The tuning engine is configured to identify at least one filter coefficient based on the performance metric values using a simplex algorithm. The tuning engine is configured to communicate the at least one updated filter coefficient to the transmit filter for storage in the register.
Pam-4 Data Slicer Having Symmetrical Offset
US Patent:
7283596, Oct 16, 2007
Filed:
Jul 8, 2003
Appl. No.:
10/616214
Inventors:
William W. Brown - Los Altos CA, US
Assignee:
Avago Technologies General IP (Singapore) Pte Ltd - Singapore
International Classification:
H03K 9/00
US Classification:
375316, 318678, 327 52, 327 89, 327 96, 327127, 327246, 327266, 327274, 327280, 327287, 327359, 327563, 330252, 375318
Abstract:
A PAM-4 data slicer includes first, second, and third comparators which provide first, second, and third thresholds, respectively. Each of the comparators has an offset. The first and third comparators have an offset generating arrangement at their outputs to provide the first and third comparator circuits with symmetrical offsets.
