Product details
Overview
TDA10025HN/C1,557 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, QPSK–256 QAM demodulators, and Annex A/B/C FEC engines, supporting simultaneous DVB-C demodulation at 6.9 Msps per channel with total power dissipation of 235 mW (typ). Its role is physical-layer signal digitization and error-corrected transport stream generation in broadband cable receivers.
For engineers reviewing the TDA10025HN/C1,557 datasheet, TDA10025HN/C1,557 pinout, TDA10025HN/C1,557 application, or TDA10025HN/C1,557 equivalent, this page delivers verified specifications, package mapping to HVQFN48, dual-stream timing architecture, supply voltage tolerances (1.15–1.3 V / 3.0–3.6 V), and real-world STB deployment context - all critical for RF front-end integration and power budgeting.
Technical Context
The TDA10025HN/C1,557 implements two fully independent cable downstream processing paths, each with a dedicated 12-bit ADC, demodulator, and FEC engine compliant with ITU-T J.83 Annex A (Europe), Annex B (US), and Annex C (Japan). Each path supports QPSK, 16/32/64/128/256 QAM modulation schemes and includes a Transport Stream Multiplex Frame (TSMF) module for Annex C compliance.
It features an on-chip PLL for crystal frequency multiplication from a 16 MHz external reference, enables 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.

FAQ
What is the primary function of the TDA10025HN/C1,557 in a cable receiver system?
The TDA10025HN/C1,557 serves as a dual-channel cable downstream processor, performing analog-to-digital conversion, QAM/QPSK demodulation, and Forward Error Correction per channel. It processes in-band DOCSIS, EuroDOCSIS, DVB-C, and OpenCable signals to generate compliant MPEG-2 Transport Streams. Its architecture enables simultaneous decoding of two independent RF inputs - a key capability for picture-in-picture and dual-tuner STBs - and is implemented in the TDA10025HN/C1,557 with integrated PLL, TSMF, and low-power design.
Does the TDA10025HN/C1,557 support all major cable standards including regional variants?
Yes, the TDA10025HN/C1,557 supports ITU-T J.83 Annex A (Europe), Annex B (US), and Annex C (Japan) FEC standards, enabling global deployment across DVB-C, DOCSIS, EuroDOCSIS, and OpenCable platforms. The inclusion of a dedicated Transport Stream Multiplex Frame (TSMF) module ensures Annex C compliance for Japanese OpenCable systems. This multi-annex capability is built into the TDA10025HN/C1,557 silicon and does not require external firmware patches or configuration overrides.
What are the power supply requirements for reliable operation of the TDA10025HN/C1,557?
The TDA10025HN/C1,557 requires two regulated supplies: 1.2 V ±50 mV (VDD(1V2)) for the core logic and demodulation blocks, and 3.3 V ±300 mV (VDD(3V3)) for I/O, ADC reference, and TS interface circuits. Under dual-stream 256 QAM operation at 6.9 Msps, total power dissipation is 235 mW (typical), with maximum junction temperature rated at 120 °C. These values are specified in the TDA10025HN/C1,557 short data sheet and validated across process corners and temperature ranges.
How is clocking managed in the TDA10025HN/C1,557 to minimize external components?
The TDA10025HN/C1,557 integrates an on-chip PLL that multiplies a 16 MHz external crystal to generate all internal clocks, eliminating the need for external clock synthesizers. It also supports tuner clock reuse - accepting the tuner's output clock directly as a system reference - thereby removing the requirement for a second crystal oscillator. This dual-clock optimization is a defined feature of the TDA10025HN/C1,557 and contributes directly to its low-BOM-cost target for consumer STBs.
What package type and thermal characteristics does the TDA10025HN/C1,557 use?
The TDA10025HN/C1,557 is housed in an HVQFN48 (SOT619-1) package measuring 7 × 7 × 0.85 mm with an exposed thermal pad. This thermally enhanced, leadless quad flat package enables efficient heat transfer to the PCB ground plane and supports operation up to 120 °C junction temperature. The package footprint and thermal profile are documented in the TDA10025HN/C1,557 ordering information table and are consistent across all production lots.
