Implementation of change:
Expected 1st Device Shipment Date: 2007/06/06
Earliest Year/Work Week of Changed Product: H3
Change Type Description: Die Revision
Description of Change (From): Die change
Description of Change (To): Four changes were made to the current production die with metal
mask updates. Change 1: The receiver serial clock signal was delayed to better center on the
serial data. Change 2: Internal serial interconnects were re-routed for better isolation from
transient signals. Change 3: The serial standby burst source current, IODSTBY,was increased to
improve noise immunity. The serial burst source current was increased from 130uA to 200uA
typical. The master burst standby current, IBRST_M,was increased from 1.1mA to 1.3mA
typical. Change 4: ESD robustness was improved by adding a filter to ignore ESD transient
events on the serial lines.
Reason for Change : Improve RF and ESD susceptibility.
Qual/REL Plan Numbers : Q20060318
This change was qualified by similarity in die size and power dissipation to the original
