TDA10027HN/C1,518

Video Processing Overview

The TDA10027HN/C1,518 is a dual cable downstream processor designed for in-band DOCSIS, EuroDOCSIS, DVB-C, and OpenCable Set-Top Boxes. It digitizes downstream signals using embedded 12-bit ADCs and performs physical layer processing including demodulation of QPSK through 256 QAM and Forward Error Correction compliant with ITU-T J83 Annex A, B, and C. The device features an Out-Of Band receiver with a QPSK demodulator and 10-bit ADC supporting SCTE55-1/2 standards. Operating on 1.2 V and 3.3 V supplies, it consumes approximately 260 mW during dual stream operation.

Video Processing Feature Summary

• Dual channel architecture enabling simultaneous demodulation of two independent cable downstream streams.
• Integrated analog-to-digital conversion with dedicated 12-bit ADCs for main channels and a 10-bit ADC for the OOB receiver.
• Comprehensive forward error correction capabilities covering multiple regional standards and transport stream multiplexing.
• On-chip phase-locked loop allowing reuse of tuner clock to reduce external component count.

Video Processing Applications

• In-band DOCSIS and EuroDOCSIS Cable Modems
• DVB-C Digital Video Broadcasting Set-Top Boxes
• OpenCable Interactive Platform devices

Video Processing Procurement Notes

Verify current product status as this component may be subject to obsolescence or discontinuation. Confirm package availability and lead times directly with NXP Semiconductors or authorized distributors before design finalization. Ensure compliance with RoHS and REACH regulations applicable to your region. Review the latest datasheet revision for any updates to electrical characteristics or pin definitions prior to implementation.

Video Processing Selection Notes

Select this component for designs requiring high integration of dual-channel cable demodulation within a single silicon solution. It is suitable for applications needing support for various QAM modulation orders up to 256 QAM. Consider the low power consumption profile for battery-operated or thermally constrained environments. Verify that the HVQFN64 package fits the PCB layout constraints and thermal management requirements of the target system.
