P-44: Electromagnetic Interference (EMI) Suppression in an Intra-Panel Interface with Periodic Clock-Embedded Signaling Scheme

An intra-panel interface system employing data scrambling for EMI suppression is presented in this work. The proposed data scrambler targets two sources of EMI found in a periodic clock-embedded interface system: active data field and horizontal blanking period (HBP). For verification, an intra-panel interface based on enhanced Reduced Voltage Differential Signaling (eRVDS) with data scrambling function is implemented in CMOS technology, and EMI measurement of the prototype shows that suppression of data-induced EMI can be successfully achieved by the proposed scrambling technique.
