It is supported under Linux by the bttv kernel driver module.
The Bt848 chip was used by many analog cards produced in the mid 1990's; which collectively help constitute the Bttv devices categorization.
Both the Bt848A and Bt849A chip variations included all the features of Bt848 while adding support for a few more functions (summarized in the table below).

The Bt848 would also become the basis for several other successive decoder chipsets, beginning with the Brooktree Bt878; which themselves would also prove to be widely utilized.
