Abstract
Crosstalk amelioration systems and methods in a radio frequency front end (RFFE) communication system provide a host or master of an RFFE bus to monitor a weakly-driven data line in the RFFE bus while a clock line is actively providing a clock signal for trigger events at one or more slaves on the RFFE bus. If the host detects noise on the data line that looks like a sequence start condition (SSC) signal, the host further signals on the data line to negate the impact of the false SSC signal and thus avoid misinterpretation by the slaves.
