TDA10026HN: Single cable demodulator with Out-Of Band receiver ARCHIVED

Overview

Archived content is no longer updated and is made available for historical reference only.

The TDA10026HN is a Single Cable Downstream Processor.

The Cable Downstream Processor (CDP) implements the physical interfaces and protocols required to provide the highest quality services of an in-band DOCSIS, EuroDOCSIS, DVB and OpenCable Set-Top Box (STB). The downstream signals are digitized by 12-bit ADC and passed to the Demod and Forward Error Correction (FEC) blocks, which do all the cable physical layer processing. This processing includes demodulating and Annex A (Europe), Annex B (US) or Annex C (Japan) FEC for the in-band data.

The Out-Of Band (OOB) receiver consists of a QPSK demodulator with FEC, compliant to SCTE55-1 and SCTE55-2 standards, with either internal MAC or POD support. Data are digitized by a 10-bit ADC.
