LMH0318、LMH1218电源问题咨询

Other Parts Discussed in Thread: LMH1218, LMH0318, LMH1219

在LMH0318、LMH1218的datasheet中,有关电源的部分提到:

9 Power Supply Recommendations
Follow these general guidelines when designing the power supply:
1. The power supply should be designed to provide the recommended operating conditions in terms of DC
voltage, AC noise, and start-up ramp time.

当中的start-up ramp time没有在datasheet中找到描述,是否对这个有要求呢?如果没有要求的话,VDD的2.5V的 ramp time是否可以是100ms或更大?芯片是不是只会在VDD大于2.375V时才开始工作的呢?

另外同类接口芯片LMH1219中却没有提到start-up ramp time这项,是不是也有要求呢?
