Si2165 デモジュレータ(DVB-T/C)

Si2165 digital TV demodulators 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 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.

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, enabling the use of Si2165 with any TV tuner, either metal can or silicon tuner based. In addition to DVB-T's 2 K and 8 K FFT modes, Si2165 devices include a 4 K FFT mode, “native” and “in-depth” deinterleavers and extended TPS to be compliant with DVB-H (EN 300 744 Annex F), allowing it to receive DVB-H programs in fixed receiver applications (without decoding DVB-H's additional MPE FEC layer). Si2165 devices are pin-for-pin compatible and support all modes of DVB-T (EN 300 744), including hierarchical modes, and ITU J.83 annex A/C and DVB-C (EN 300 429), including a user-configurable 31-tap equalizer. With its minimal BOM and very small package footprint (5 x 6 mm, 36-pin QFN), Si2165 guarantees a low-cost system implementation. When Si2165 demodulators are paird with the Si217x hybrid TV tuner, a complete hybrid PAL/SECAM and DVB-T/C receiver (NIM or on-board) is provided.
