From what I have read, the ATEM will generate and embedded TC out on the HD-SDI outputs to allow the three recordings to be lock together in post for editing? No external hardware is required to generate TC to input to the Hyperdecks?
Yes, the ATEM 1 M/E 4K will begin generating timecode at startup and will embed this timecode on the AUX and SDI Program outputs.
With ATEM software version 8.0 or higher you can set the starting timecode value (and restart the built-in timecode generator) through the ATEM Software Control Panel. Since this ATEM model doesn't have an external timecode input, that can make it difficult to sync to an external timecode source (such as the internal recording on a camera, a standalone audio recorder, or dedicated timecode generator).
But everything should work fine as long as the video you want to record comes from one of the ATEM's SDI Program or AUX outputs. You will just have to make sure that you set your HyperDeck Studio Pro's to use the SDI input as the timecode source (rather than the external timecode over the XLR connector that is also supported on these units).
