Overview of DRX-D

The Micronas DRX-D is a DVB-T demodulator chip and has been used on PCIe cards along with the nGene PCIe interface, and USB 2.0 sticks.

Cards based on nGene / DRX-D

The following nGene-based cards are known to exist:

	Terratec Cinergy 2400i DT	K-World PlusTV DVB-T 210R	Compro VideoMate E700
Form Factor	Full Height PCIe	Half-height PCIe	Half-height PCIe
Driver	Terratec-specific INF, regular Micronas driver	Micronas reference driver and INF	Compro-specific INF and driver naming
Tuner	2x Thomson DTT7520	2x Microtune MT2060	2x Microtune MT2060
Demodulator	2x Micronas DRX3975D A2	2x Micronas DRX3975D B1	2x Micronas DRX3975D
Chipset	Micronas APB7202A	Micronas APB7202A	Micronas APB7202A

The first nGene card, the Prolink/PixelView PlayTV PCX600 was shown at CeBIT 2005 but it seems that it never made production. The first production nGene card is the Terratec Cinergy 2400i DT and is still in production as of December 2008.

The DRX3975D demodulator is also used in some USB 2.0 sticks (not Micronas nGene based) such revision B of the Hauppauge HVR-900 hybrid stick.

Linux Support

Linux support for Micronas hardware is very difficult because Micronas seem unwilling to release documentation for their hardware. It is a shame that the company takes this view because the quality of the hardware is very good to excellent (on Windows). The nGene is completely unsupported. Support for the DRX3975D exists for certain USB sticks (e.g. Hauppauge WinTV HVR-900) but has been reverse engineered from the Windows driver. A binary driver exists for the Terratec Cinergy 2400i DT, but no source code is available.
