TechnoTrend TT-connect CT2-4650 CI is an USB DVB-T2/C tuner with the following components:
USB interface: Cypress CY7C68013A-56LTXC Demodulator: Silicon Labs Si2168-A20 Tuner: Silicon Labs Si2158-A20 CI chip: CIMaX SP2HF The firmware for the tuner is the same as for TechnoTrend TT-TVStick CT2-4400. See https://www.mail-archive.com/linux-media@vger.kernel.org/msg76944.html The demodulator needs a firmware that can be extracted from the Windows drivers. File ttConnect4650_64.sys should be extracted from http://www.tt-downloads.de/bda-treiber_4.1.0.4.zip (MD5 sum below). 3464bfc37a47b4032568718bacba23fb ttConnect4650_64.sys Then the firmware can be extracted: dd if=ttConnect4650_64.sys ibs=1 skip=273376 count=6424 of=dvb-demod-si2168-a20-01.fw The SP2 CI module requires a definition of a function cxusb_tt_ct2_4650_ci_ctrl that is passed on to the SP2 driver and called back for CAM operations.
