Abstract
In an integrated circuit arrangement with a plurality of signal connections linked to the inputs of a multiplexer, overmodulation of the signal connections can lead to crosstalk between multiplex channels. The new procedure should suppress such crosstalk. In order to avoid overmodulation, the voltages at the signal connections are limited to permissible input voltage values, while each overmodulated signal connection is configured as an output and, depending upon the overmodulation, set to a high or low level. Whereby, in order to test whether a signal connection is overmodulated, the input voltage value at this signal connection is converted to a digital data value which, because of its final bit width, lies within a data range limited by an upper and lower data limit value. If the data value equals the upper or lower data limit value, this is interpreted as overmodulation of the relevant signal connection.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
