Would like to check if there any recommendation on the acceptable length for PDM bus, using MP23DB01HP.

Welcome, @YChri.3, to the community!
Please keep in mind that the clock frequency on the single ended line is 1...3.25MHz and the maximum load capacity at the output is 100pF. Additional lines add capacity, which affects the signal quality, so that a detailed examination is necessary for lines longer than approx. 20cm. If necessary, the use of termination resistors could also be useful.
