Product details
Overview
TDA10025HN/C1,551 from NXP Semiconductors is a dual-channel cable downstream processor IC for DOCSIS/EuroDOCSIS/DVB-C/OpenCable set-top boxes. It integrates two independent 12-bit ADCs, QAM demodulators (QPSK to 256 QAM), and Annex A/B/C FEC engines, enabling simultaneous demodulation of two DVB-C streams at 6.9 Msps (256 QAM) with total power dissipation of 235 mW typical.
For engineers reviewing the TDA10025HN/C1,551 datasheet, TDA10025HN/C1,551 pinout, TDA10025HN/C1,551 application, or TDA10025HN/C1,551 equivalent, key selection criteria include dual-stream DVB-C demodulation capability, ITU-T J.83 Annex A/B/C compliance, embedded 12-bit ADC, HVQFN48 thermal-enhanced package, and low-power 1.2 V/3.3 V dual-supply operation.
Technical Context
The TDA10025HN/C1,551 implements two fully independent Cable Downstream Processor (CDP) channels, each comprising a 12-bit ADC, demodulator supporting QPSK/16–256 QAM, and dedicated Forward Error Correction engine compliant with ITU-T J.83 Annex A (Europe), Annex B (US), and Annex C (Japan). The Annex C path includes a Transport Stream Multiplex Frame (TSMF) module for OpenCable compliance.
It features an on-chip PLL for crystal frequency multiplication (16 MHz external reference), supports tuner clock reuse to eliminate a second crystal, and provides configurable TS interface modes - time-interleaved parallel or serial - with I²C-bus configuration and centralized clock/reset distribution via CGU and RGU blocks.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Demodulation Modes | QPSK, 16/32/64/128/256 QAM per channel - enables full compatibility with global DVB-C and DOCSIS in-band physical layer standards. |
| FEC Compliance | ITU-T J.83 Annex A, B, and C - ensures interoperability across European, North American, and Japanese cable infrastructure deployments. |
| ADC Resolution | 12-bit integrated ADC per channel - delivers sufficient dynamic range for high-SNR cable signal digitization without external converters. |
| Power Dissipation | 235 mW typical (dual 256 QAM @ 6.9 Msps) - enables thermally constrained STB designs with minimal heatsinking. |
| Supply Voltages | 1.2 V (±0.1 V) and 3.3 V (±0.3 V) - supports modern low-voltage digital logic and mixed-signal partitioning with separate analog/digital domains. |
| TS Interface | Time-interleaved parallel or serial mode - offers flexible integration with MPEG-2 transport stream processors and SoCs. |
| Junction Temp Limit | 120 °C maximum - defines thermal design margin for continuous dual-channel operation in sealed consumer enclosures. |
Pinout & Package
HVQFN48 plastic thermal-enhanced very thin quad flat package; no leads; 48 terminals; body 7 × 7 × 0.85 mm (SOT619-1). Exposed thermal pad improves thermal resistance for sustained dual-stream operation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|

| VDD(3V3) | I/O and analog supply | 3.3 V power for ADC analog front-end, TS interface drivers, and I²C I/O; separate from core supply. |
| ADC_IN0 / ADC_IN1 | Analog RF inputs | Differential baseband inputs for two independent cable channels; DC-coupled, require external anti-alias filtering. |
| TS0 / TS1 | Transport Stream outputs | Parallel or serial MPEG-2 TS outputs per channel; configurable timing and data width via register settings. |
| SCL / SDA | I²C-bus interface | Standard bidirectional I²C interface for configuration, status readback, and real-time parameter adjustment. |
| XTAL_IN | Crystal oscillator input | 16 MHz fundamental-mode crystal connection; internal PLL multiplies to generate all internal clocks. |
Key Features
| Feature | Design Value |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-cable-demodulator applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STi5518 | Single-channel DVB-C demodulator with integrated MPEG-2 decoder; no Annex B/C support; requires external ADC. | Limited to single-stream DVB-C; lacks DOCSIS/EuroDOCSIS/OpenCable multi-standard support. | Select when only one demodulated stream is needed and MPEG decode is required on-die. |
| BCM3460A | Dual-channel QAM demodulator with 10-bit ADC; supports Annex A/B only; no TSMF or Annex C hardware acceleration. | Not suitable for OpenCable (Annex C) deployments; lower ADC resolution reduces SNR margin in noisy cable plants. | Choose for cost-sensitive US-market DOCSIS/EuroDOCSIS gateways where Annex C is not required. |
Compared with STi5518 and BCM3460A, the TDA10025HN/C1,551 uniquely delivers dual-channel 12-bit ADC-based demodulation with full Annex A/B/C FEC and hardware TSMF - making it the only option qualified for global multi-standard STBs requiring simultaneous DVB-C, DOCSIS, and OpenCable support.

FAQ
What modulation schemes does the TDA10025HN/C1,551 support?
The TDA10025HN/C1,551 supports QPSK, 16-QAM, 32-QAM, 64-QAM, 128-QAM, and 256-QAM demodulation per channel. This full range enables compliance with DVB-C, DOCSIS, EuroDOCSIS, and OpenCable physical layer specifications across Europe, North America, and Japan. Each channel operates independently, allowing simultaneous demodulation of different modulation types if configured accordingly in the host system.
Does the TDA10025HN/C1,551 include an integrated ADC?
Yes, the TDA10025HN/C1,551 integrates two independent 12-bit analog-to-digital converters - one per downstream channel. These ADCs digitize baseband cable signals directly, eliminating the need for external ADC components and simplifying analog front-end design. The 12-bit resolution provides adequate dynamic range for high-SNR demodulation in typical cable plant environments.
What is the power consumption of the TDA10025HN/C1,551 during dual-stream operation?
The TDA10025HN/C1,551 consumes 235 mW typical total power during dual-stream operation with 256-QAM at 6.9 Msps per channel. This value assumes 1.2 V and 3.3 V supplies at nominal voltage. Power varies with modulation type, symbol rate, and enabled features - standby mode draws only 10 mW typical with all ADCs and clocks disabled.
Which cable standards does the TDA10025HN/C1,551 support?
The TDA10025HN/C1,551 supports ITU-T J.83 Annex A (Europe), Annex B (US), and Annex C (Japan) Forward Error Correction, enabling full compliance with DVB-C, EuroDOCSIS, DOCSIS, and OpenCable standards. Its TSMF module provides hardware-level Annex C transport stream framing, a mandatory requirement for OpenCable STB certification in Japan.
What package type is used for the TDA10025HN/C1,551?
The TDA10025HN/C1,551 uses the HVQFN48 package (SOT619-1): a 7 mm × 7 mm × 0.85 mm thermal-enhanced very thin quad flat no-lead package with 48 terminals and an exposed thermal pad.
