PDF-MPR121 Jitter and False Touch Detection

INTRODUCTION Touch acquisition takes a few different parts of the system in order to detect touch The baseline filter and touch detection atightly coupled The purpose of the touch detection block is. 5 15 25 35 Jitter Freqiency in MHz RMS Jitter Sensitivity in picoseconds Jitter Measurements Using Phase Locked Loops Z ZQZ Z QQZ Z 587Z Z Q DUT Direct Low Jitter Reference Oscillator Phase Detector Loop Filter Measurement Filter Output at this p MPR121 ; On the other side, it Zhang. yanqing@virginia.edu.
