TDA10025HN/C1,557

Video Processing Overview

The TDA10025HN is a dual cable downstream processor designed for in-band DOCSIS, EuroDOCSIS, DVB, and OpenCable Set-Top Boxes. It digitizes downstream signals using embedded 12-bit ADCs before passing data to demodulation and Forward Error Correction (FEC) blocks. The device supports QPSK, 16/32/64/128/256 QAM demodulation and ITU-T J83 Annex A, B, and C FEC standards. It operates on 1.2 V and 3.3 V supplies with total power dissipation of 235 mW for dual stream operation at 256 QAM 6.9 Msps. The component is housed in an HVQFN48 package.
