K4 Sound Card, used for Weak Signal Digital Modes.

Andy:  In answer to your two questions:

The TI PCM2901, I am told by a Watsonville rep, was used in the K3-S.
Whether it was used in early production runs, or used in later production
runs, I do not know.  It comes in two versions: Model E and Model EG4.  The
data sheet and other specs can be found here :

As far as your second question:  Do not know.  My guess is that the K4 will
have a different, later-model chip altogether.
