The range of calibration time of RX DCK is quite wide from ~40us to ~1300us by experiments, and probability is about 0.1% for the cases larger than 1000us. Though it can retry calibration and get positive result, it will spend more time. Therefore, enlarge it to avoid warning and duplicate calibration.
