TPS55340-Q1: Max SYNC frequency

Hello, I wish to use the TPS55340-Q1 in sync with other supplies (TPS63020-Q1), which accepts a sync frequency of 2.4MHz +/- 200 kHz. The TP55340-Q1 would work for my application, however, there are discrepancies in the datasheet regarding the maximum SYNC frequency:

P.1: Max frequency: 2.5 MHz

P.3: The Sync pins accepts SYNC input up to 1MHz (corrected in the related post to 2 MHz)

P.10: Above 1.2 MHz, TI recommends using and external clock signal (which lead to the related question)

So, I would like an update on the TRUE maximum switching and SYNC frequencies, so that I know if I can use the same 2.4 MHz signal for all my regulators, or if I'll need a 1.2 MHz clock for the TPS55340-Q1.

Thanks!
