Product short data sheet
1. General description
The TDA10025HN is a Dual 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.
2. Features and benefits
QPSK, 16 QAM, 32 QAM, 64 QAM, 128 QAM and 256 QAM Demodulator
ITU-T J83 Annex A, B and C FEC
Transport Stream Multiplex Frame (TSMF) module for Annex C compliance
Time interleaved parallel mode or serial mode for Transport Stream (TS) interface
On chip PLL for crystal frequency multiplication (16 MHz external)
Reuse of the tuner clock, saving one crystal
Embedded 12-bit ADC
3.3 V and 1.2 V power supplies
Low power < 235 mW for dual stream operation
Small size package
Low cost Bill Of Material (BOM)
