Both of those are very uncommon choices for current silicon RF tuners. Si2157 is very modern RF tuner which runs firmware and has has a DSP for digital filtering (and more?). I2C bus is coming through the Si2168 demodulator, chip on the right side. Metal box, just upper-side of chip, is crystal which offers 24 MHz reference clock. Silicon Labs Si2157 & Silicon Labs Si2168Ĭhip "215730" seen on picture is Silicon Labs Si2157 RF tuner. Demodulator, RF tuner and LNA are all here. That PCB is practically dedicated for RF parts "tuner". However, attaching sniffer to second I2C bus is even more easier as that bus is routed to another PCB via those soldered pin headers. First bus is for eeprom and all the rest are on second bus. Copper pads are debug pins, attach your sniffer there :) It is not possible sniff demodulator and tuner from that point because only eeprom is connected to this bus. I2C bus itself goes through PCB directly to eeprom located just other side of PCB. It is those two long wires going from chip to right on picture and ending right side of "PCTV" text. I2C bus wires from EM28178 to eeprom are clearly visible.

I2C serial eeprom is located on main PCB, but it is bottom side - between the PCBs. It cannot be LNA as RF parts are located on another PCB. Unfortunately that chip printings are too unclear and I cannot guess what it is. There is another 10 pin chip too, located right side of EM28178. Clock source is crystal (it should be 12 MHz) which is located on same PCB, but bottom side, between the "sandwich". Biggest chip clearly visible is EM28178.ĮM28178 is USB-bridge, maybe the latest version from Empia EM28xx family. Earlier, Pinnacle also used that kind of sandwich construction, maybe its backgrounds are from there, dunno ( PCTV Systems was Pinnacle). It is somehow popular construction only for PCTV Systems and Hauppauge devices. That device is build to two PCBs, which are attached together like a sandwitch. Initial Linux support will go the Kernel 3.16 if nothing unexpected happens.
Stick PCB also has model number 291e printed.
#Pctv systems kodi driver#
According to Windows driver tripleStick, 292e, seems to be just renamed 291e for the reason or the other. Windows driver knows also USB ID 2013:025b for 291e. PCTV Systems has assigned USB ID 2013:025f for that device. So, I decided to give a try for reverse-engineering that Silicon Labs DTV chipset open. My initial plan was not write driver for tripleStick, but I changed my mind after large amount of feedback from users who has ordered old well supported nanoStick T2, but got non-working tripleStick instead. nanoStick T2 has been very popular stick among the Linux users as it have been basically the only one DVB-T2 capable stick which works out of the box ( I made its driver for Kernel 3.0). If you now order nanoStick T2 you will likely get tripleStick as a replacement. It replaced rather quickly old nanoStick T2. That device appeared to market beginning of this year, during January 2014 or so.
Only differences seems to be colored logo on upper-side and model number (290e vs. Case is just similar and it is hard to distinguish visually between nanoStick T2 and tripleStick. It has a little bit better features compared to old nanoStick T2 as nanoStick T2 didn't support officially DVB-C at all, only DVB-T and DVB-T2. TripleStick is the latest DVB-T/T2/C stick from PCTV Systems, successor of the old good PCTV nanoStick T2 (290e).
