LSF0102: A glitch during power up

Part Number: LSF0102
Other Parts Discussed in Thread: SN74AUP1G126

Hi Team,

My customer found a glitch issue when power up LSF0102.

Here is the circuit, customer has changed R998 from 100K to NC, R128 from NC to 10K.

There is a glitch at A1 pin when VREF_A is powered up, it seems A1 pin raises through pull up resistor R128 before LSF0102 is enabled. Does power up sequence needed? Or, any other method can prevent this issue?

Thanks a lot.
