Micronas DRX-J digital TV demodulators (Hauppauge WinTV-HVR-950Q class)
A family of Micronas DRX39xxJ digital television demodulator chips from around 2005, used to decode over-the-air ATSC and QAM cable broadcasts inside consumer TV tuner products such as the Hauppauge WinTV-HVR-950Q and 955Q USB sticks, PC-TV cards, set-top boxes, and PVRs sold through the late 2000s and 2010s.
recommendation
Worth keeping but documenting its niche, because while upstream is still receiving routine cleanup and bug-fix work through 2024, the hardware itself is a 2005-era consumer DTV chip family that powered USB tuner sticks like the Hauppauge WinTV-HVR-950Q/955Q, which retailers now list as discontinued. The remaining audience is people running long-lived ATSC/QAM tuner sticks rather than anyone buying new hardware.

LKDDb shows CONFIG_DVB_DRX39XYJ remains present through current kernel HEAD, indicating the driver is still carried upstream.

Vendor news identifies the DRX-H/DRX family as a 2005-era Micronas consumer DTV demodulator line for HDTVs, set-top boxes, PC-TV cards, PVRs, and tuner modules.

Hauppauge still publishes support material for WinTV-HVR-950Q/955Q class devices, consistent with a remaining installed base rather than active mainstream new deployment.

A reseller page marks WinTV-HVR-950Q as a discontinued product, supporting the conclusion that this hardware family is legacy rather than newly sold.
codex reasoning notes (technical)
Local shell inspection (`rg` in the directory) shows this is real frontend driver code and names the device as "Micronas DRX39xxj family Frontend" with Hauppauge references in source. Local shell `git -c safe.directory=... log --since=2021 -- drivers/media/dvb-frontends/drx39xyj` shows non-removal upstream attention through 2024-2026, mostly cleanup/bug-fix work and no visible removal push; `lei` was unavailable in the environment, so lore-specific lookup could not be run. URLs were obtained via web search: LKDDb for continued upstream presence, Micronas/TDK vendor history for chipset era and market, Hauppauge support plus reseller discontinuation evidence for present-day legacy deployments. Because maintenance is still happening but the hardware is clearly old consumer-TV silicon with only residual installed-base relevance, the right call is keep-annotate rather than deprecate/remove.
