​Si2165/63/61-D Demodulators (DVB-T/C, DVB-C and DVB-T)

​The Si2165/63/61 digital TV demodulator products are the most compact, lowest power and highest performance combo demodulator solutions for DVB-T/H, DVB-T/C/H (fixed reception for DVB-H).
​Si2165, Si2163 and Si2161 demodulators are ideal for equipment receiving digital terrestrial and/or cable services, including Free-to-Air (FtA) or pay-TV set top box receivers, iDTVs, PC-TV cards, DVD/HDD personal video recorders, portable media players, portable DVD players, digital picture frames and automotive receivers.

Technologies

  • DSP-based synchronization and control with embedded firmware in ROM avoids need for code download at startup
  • On-chip ultra fast automatic UHF/VHF band scanning (QuickScan)
​The analog front-end consists of two ADCs with wide dynamic range (12-bit) to allow operation with standard IF (~36 MHz), low-IF or zero-IF inputs. This enables the use of the Si2161 and Si2165 with any TV tuner, either metal can or silicon tuner based. The multi-standard demodulator supports all modes of DVB-T (EN 300 744), including hierarchical modes. In addition to DVB-T's 2 K and 8 K FFT modes, the Si2161 and Si2165 also includes a 4 K FFT mode, “native” and “in-depth” deinterleavers and extended TPS to be compliant with DVB-H (EN 300 744 Annex F). The Si2161 and Si2165 can then receive DVB-H programs in fixed receiver applications (without decoding DVB-H's additional MPE FEC layer).
The Si2165 also supports ITU J.83 annex A/C and DVB-C (EN 300 429), including a user-configurable 31-tap equalizer. The Si2161 and Si2165 guarantees a low-cost system implementation due to its minimal BOM and very small package footprint (5 mm x 6 mm, 36-pin QFN). Both the Si2161 and Si2165 are pin-for-pin compatible.
A complete hybrid PAL/SECAM and DVB-T/C receiver (NIM or on-board) is provided when the Si2161/5 demodulator is paired with the Si217x hybrid TV tuner.
