Difference between LTC2325-12 and AD9637 synchronous sampling

Our company chooses an 8-channel ADC that can be sampled at the same time, and sees LTC2325-12 and AD9637-40. I would like to ask you some questions about these two ADC chips.

What's the difference between LTC2325-12 and AD9637-40? What's the difference between them when sampling synchronously?

LTc2325-12 synchronous sampling can retain phase information, so can AD9637's 8-channel colleagues retain phase information when sampling?

Thank you very much for your help in answering these questions.

As we are in a hurry, I hope you can reply to me as soon as possible. Thank you very much.
