TDA10025HN/C1,518

Video Processing Overview

The TDA10025HN is a dual cable downstream processor designed for in-band DOCSIS, EuroDOCSIS, DVB, and OpenCable Set-Top Box applications. 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. The component is housed in an HVQFN48 package.

Video Processing Feature Summary

• Dual-channel architecture supporting simultaneous DVB-C demodulations

• Supports multiple modulation schemes including QPSK and up to 256 QAM
• Compliant with ITU-T J83 Annex A, B, and C forward error correction standards

Video Processing Applications

• In-band DOCSIS Set-Top Boxes
• EuroDOCSIS Set-Top Boxes
• DVB Cable Set-Top Boxes
• OpenCable Set-Top Boxes

Video Processing Procurement Notes

Verify the specific ordering suffix /C1,518 against official NXP documentation to confirm package type and tape/reel specifications. Ensure compatibility with required supply voltages of 1.2 V and 3.3 V during design integration. Confirm that the HVQFN48 package dimensions align with PCB layout constraints.

Video Processing Selection Notes

Select this component for designs requiring dual independent downstream processing channels within a single integrated circuit. It is suitable for applications needing support for various regional cable standards defined by ITU-T J83 Annexes A, B, and C. Consider the low power consumption profile when thermal management is a priority in compact Set-Top Box form factors.

Video Processing Part Context
