E3C EC168

An USB controller, that also contains an embedded DVB-T demodulator, produced by Tai-Hui and marketed under the brand name e3C Technologies.

This IC is used in many cheap DVB-T USB Sticks. Support is currently very experimental under Linux. (Only the combination with MXL5003S will work and only with 7 and 8 MHz channels.)

EC168 Devices

Note: The list of devices here is quite a mess. Mostly because cheap EC168 devices are sold under a bazillion different pseudo brands and generic names. That makes it hard to trace the original manufacturer. So if you know any better please correct the manufacturer/oem information on this page.

If you own such a device please check the pictures below to see if your device is already here.
- If it is then please add the brand and device name you bought it as.
- If your device is not yet here please open it up and see whats inside. (Sometimes the plasic case can differ but the innards are just the same.)

And please, if your device or its PCB differ from the ones that are here, please take some pictures and add them.

Known USB IDs are 18b4:1689, 18b4:fffa, 18b4:fffb, 18b4:1001 and 18b4:1002 (for devices with a second tuner).

Misc. Devices

If you own one of these devices, please add the missing information and make a subsection for them, or add them to the appropriate device subsection.

SinoVideo SV3420D

USB ID: 18b4:1689 Tuner: MXL5003S

The PCB says SV3420D-V02.

Apparently produced by SinoVideo and sold under lots of different names.

Manufacturer(?)

As the windows driver CD is labeled SV3420A and timestamps are rather old, I suspect that the drivers didn't change since SV3420A. Equally the Linux driver should work for all revisions. Remote control part is recognized as HID device by the kernel.

Works with the driver from Antti's mercurial repository as described in [6]

Sweex MM002V2

USB ID: 18b4:1689

Tuner: Microtune MT2060

Works with the driver from Antti's mercurial repository as described in [7] with Ubuntu 9.04 (linux 2.6.18-24). Firmware on the original CD didn't seem to work, but the firmware on palosaari.fi does work.

Note that under Windows, the red light on the usb stick lights up, under linux it stays dim all the time (but watching TV with mplayer is just fine)

WS-DVBTM2 Tevion USB-DVB-T

Cheap offer at Hofer (Aldi) in Austria. Has an EC168 and MXL5003s built in, which refers to the E3C reference design. Reffering to the link, the system only freezes after loading the dvb-usb-ec168.ko module under debian 5.0 unstable. All other modules load fine. Maybe other distros and/or hardware has better success. It's even impossible to load the firmware via dfu-ec168

DUTV007B USB TNT Basic LIGHT from PC-Basic (Graphics)

Same USB descriptors as SinoVideo 3420A-2, but with another PID... IR is detected directly by the hidraw driver (usbhid)

The PC-Basic v4 USB Stick contains following chips :

EC168 (USB 2.0 µ-controller, could be also a preprogrammed AVR or PIC)
Maxlinear MXL5003S Tuner [8]
EEPROM 24C02N I²C 0xA0 (256 Bytes) [9]

The windows driver also upload a 7109-bytes sized firmware (EC168BDA.bin) to get the device working...

Uploading Firmware to the device

EC168 Direct Firmware Upload tool based on libusb by Tanguy Pruvot : dfu-ec168

Something interresting with this device : We can patch USB ID and descriptors included in the firmware and/or device memory...

"ZAP" USB DVB-T Receiver

Externally identical to the Sinovideo SV3420D above (except the "ZAP" branding). Internally, the PCB is different, the chips are different.

(The PCB has the same main components, but is more heavily populated with resistors, etc. Picture is pending.)

Device ID: 18b4:fffb Tuner: Microtune MT2061F (Microtune MT2060 variant?)

The firmware file EC168BDA.bin (7109 bytes, MD5:ac4392d38f63cfbd81a97e32e55743aais) is included with the windows driver, together with a 128-byte EEPROM.bin file.
