Product details
Overview
TDA10025HN/C1,518 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, supporting simultaneous DVB-C demodulation at 6.9 Msps per channel in a single HVQFN48 package.
For engineers reviewing the TDA10025HN/C1,518 datasheet, TDA10025HN/C1,518 pinout, TDA10025HN/C1,518 application, or TDA10025HN/C1,518 equivalent, key selection criteria include dual-stream power efficiency (<235 mW), ITU-T J.83 Annex A/B/C compliance, embedded PLL clock multiplication, and transport stream interface flexibility (serial/parallel TS output).
Technical Context
The TDA10025HN/C1,518 implements two fully independent cable downstream processing paths, each with a dedicated 12-bit ADC, demodulator, and FEC decoder supporting QPSK through 256 QAM modulation schemes. It natively handles ITU-T J.83 Annex A (Europe), Annex B (US), and Annex C (Japan) physical layer standards, including TSMF processing for Annex C compliance.
Its clock architecture includes an on-chip PLL for 16 MHz crystal multiplication and tuner clock reuse capability, eliminating a second crystal. The device outputs standardized MPEG-2 transport streams via configurable serial or time-interleaved parallel interfaces, managed by dedicated Transport Stream Multiplex Frame (TSMF) modules per channel.

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; requires dual ICs for equivalent functionality; no Annex C TSMF support | Limited to Annex A/B only; lacks hardware transport stream multiplexing | Select when cost-per-channel is prioritized over integration and Annex C compliance |
| MAX2165 | RF tuner + IF demodulator combo; no integrated FEC or TS interface; requires external FEC ASIC | Targets hybrid analog/digital STBs; not DOCSIS-compliant out-of-box | Select when system uses legacy analog baseband or requires custom FEC implementation |
Compared with STi5518 and MAX2165, the TDA10025HN/C1,518 delivers higher integration (dual-channel + FEC + TS + PLL in one HVQFN48), lower total power (235 mW vs. >400 mW for dual STi5518), and native Annex C readiness - reducing BOM, layout area, and firmware development effort for global cable STB platforms.

FAQ
What modulation schemes does the TDA10025HN/C1,518 support?
The TDA10025HN/C1,518 supports QPSK, 16-QAM, 32-QAM, 64-QAM, 128-QAM, and 256-QAM demodulation per channel. This full-range QAM support enables compliance with DVB-C, DOCSIS, EuroDOCSIS, and OpenCable standards across Europe, North America, and Japan. Each channel operates independently, allowing simultaneous demodulation of different modulation types if required by system architecture.
Does the TDA10025HN/C1,518 require an external crystal oscillator?
The TDA10025HN/C1,518 requires a 16 MHz external crystal but integrates an on-chip PLL for frequency multiplication, eliminating the need for a separate high-frequency clock source. It also supports tuner clock reuse, allowing the device to synchronize to the tuner's IF clock - reducing total crystal count to one in most STB designs and simplifying clock tree layout for the TDA10025HN/C1,518.
What transport stream interface options does the TDA10025HN/C1,518 provide?
The TDA10025HN/C1,518 offers both serial and time-interleaved parallel transport stream (TS) output modes. In parallel mode, it delivers 8-bit TS data per channel with separate sync and clock signals; in serial mode, it outputs a single serialized TS stream. Configuration is performed via I²C, and the TSMF modules ensure precise Annex C frame alignment regardless of selected interface mode for the TDA10025HN/C1,518.
Is the TDA10025HN/C1,518 qualified for automotive applications?
No, the TDA10025HN/C1,518 is not automotive-qualified. Per NXP's official documentation, it is intended for consumer set-top box and residential gateway applications only. It has not undergone AEC-Q100 stress testing or temperature grading for automotive environments. For automotive infotainment systems requiring cable demodulation, alternate automotive-qualified components must be selected instead of the TDA10025HN/C1,518.
How is power managed in standby mode for the TDA10025HN/C1,518?
In standby mode, the TDA10025HN/C1,518 disables all clocks and places all three ADCs into power-down state, reducing total power dissipation to 10–30 mW. This low-power state maintains register configuration and I²C accessibility while minimizing energy consumption during tuner idle periods - critical for meeting EU ErP Lot 6 standby power requirements in STB designs using the TDA10025HN/C1,518.
