Product details
Overview
TDA8262HN/C1,118 from NXP Semiconductors (formerly Philips Semiconductors) is a fully integrated direct-conversion QPSK/8PSK satellite tuner IC for digital TV broadcasting, supporting DVB-S, DVB-S2, DBS, and BS digital standards. It operates across 950–2175 MHz, delivers I/Q baseband outputs with programmable 5–36 MHz low-pass filtering, and integrates an LC VCO, LNA, RF loop-through, and RMS input level detector. It enables dual-channel watch-and-record architectures in satellite set-top boxes.
For engineers reviewing the TDA8262HN/C1,118 datasheet, TDA8262HN/C1,118 pinout, TDA8262HN/C1,118 application, or TDA8262HN/C1,118 equivalent, this page provides verified functional context, validated pin roles, confirmed RF/baseband performance specs, and real-world tuning architecture constraints - all derived from the official Philips Semiconductors product data sheet Rev. 01 (2004).
Technical Context
The TDA8262HN/C1,118 implements a Zero-IF (ZIF) architecture with integrated quadrature LO generation from a high-performance LC oscillator, achieving <5° quadrature error and −100 dBc/Hz phase noise at 100 kHz offset. Its PLL synthesizer uses a 16 MHz crystal reference, programmable reference divider (125 kHz–2 MHz), and 15-bit main divider to tune LO frequency precisely across the full band.
RF signal path includes a switchable LNA (bypassable via 20 dB attenuation), AGC-controlled gain distribution (0–55 dB RF gain + 0–9 dB baseband gain), and on-chip RMS detector readable via I²C. Baseband outputs (IP/IN/QP/QN) drive demodulators directly, with 550 mVp-p differential swing, 1 dB I/Q amplitude mismatch, and 5° quadrature mismatch - all specified at 25°C and 3.3 V supply.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Frequency Range | 950–2175 MHz - covers all global satellite bands (EU, US, Asia) and SMA-TV standard. |
| LO Phase Noise | −100 dBc/Hz @ 100 kHz offset - ensures robust carrier recovery in high-SNR DVB-S2 8PSK reception. |
| Input Sensitivity | −70 to −15 dBm @ 75 Ω (normal mode); up to 0 dBm with 20 dB attenuation - handles strong adjacent-channel signals. |
| Baseband Filter | Programmable 5–36 MHz cut-off (32 steps) - matches symbol rates from 1 to 45 MBd without external components. |
| Supply Current | 175 mA typical (full operation); 6 mA in full power-down - enables low-power standby modes. |
| AGC Linearity | <0.7 dB/step with 8-bit DAC - preserves SNR across wide dynamic range of LNB output levels. |
| Noise Figure | 7.7–8.5 dB (typ. 8 dB) - maintains system NF budget when cascaded with LNBs having ~0.7 dB NF. |
| I²C Voltage Support | 3.3 V or 5.0 V bus compatibility - interfaces directly with legacy and modern microcontrollers without level shifters. |
Pinout & Package
Package: HVQFN32 (SOT617-1), 5 × 5 × 0.85 mm, thermally enhanced, leadless quad flat package with exposed die pad.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| RFIN (3) | RF input | 75 Ω single-ended input directly connected to LNB output; accepts −70 to 0 dBm signals. |
| RFOUT (6) | RF loop-through output | Copy of RFIN signal with 0±2 dB gain (LNA mode) or −18 dB (attenuated mode); enables dual-tuner architectures. |
| IP/IN/QP/QN (14,13,11,12) | Differential I/Q baseband outputs | 550 mVp-p differential swing; drive SDD ICs (e.g., TDA10086/TDA10093) without external amplification. |
| AGC (9) | Analog AGC control input | Voltage-controlled gain adjustment (0.3–3.0 V) from satellite demodulator; sets RF gain dynamically. |
| SCL/SDA (30,29) | I²C-bus interface | Configures PLL dividers, filters, gain, power-down states; supports 3.3 V/5 V logic levels. |
| XT/XTN/XTOUT (26,27,25) | Clock interface | 16 MHz crystal inputs (XT/XTN); XTOUT drives external demodulator's crystal input - eliminates second crystal. |
| AS (17) | I²C address select | Four selectable addresses (C0–C6 write) - allows up to four TDA8262HN/C1,118 devices on one bus. |
| CP/VT (22,20) | PLL charge pump & tuning voltage | CP outputs charge pump current; VT connects to external loop filter and VCO varicap - critical for stability. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated LC VCO | Eliminates external VCO and loop filter components; achieves −100 dBc/Hz phase noise at 100 kHz offset. |
| 20 dB LNA Attenuation Mode | Configurable via RFATT bit; prevents saturation from high-level LNB outputs (up to 0 dBm per channel). |
| Programmable Baseband Gain | 0–9 dB in 16 steps (BBGAIN[3:0]) - compensates LPF cut-off adjustments and optimizes ADC input range. |
| On-Chip RF Input Level Detection | I²C-readable RSSI (INLEVEL[1:0]) gives coarse dBm estimate (e.g., "−20 to −15 dBm") for automatic LNB biasing. |
| Four Independent Power-Down Modes | Separate control of PLL, ZIF core, loop-through, and crystal oscillator - reduces current from 175 mA to 6 mA. |
| Quadrature Error Compensation | ≤5° absolute quadrature error at 10 MHz - minimizes image rejection degradation in QPSK/8PSK demodulation. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar satellite tuner applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STV0297D | Single-conversion architecture with external IF filter; requires 5 V supply and separate VCO; no integrated loop-through. | Lacks ZIF simplicity and BOM reduction; needs additional SAW filter and level-shifting for 3.3 V systems. | Choose only if legacy 5 V design or specific IF-stage debugging capability is required. |
| MAX2104 | ZIF tuner with 950–2150 MHz range but no integrated crystal oscillator output (XTOUT); lower IIP3 (+3 dBm) and higher NF (9.5 dB). | Cannot drive external demodulator clock directly; requires external crystal buffer; less suitable for cost-sensitive dual-tuner designs. | Select when ultra-low power (120 mA) is prioritized over clock integration and linearity. |
Compared with STV0297D and MAX2104, the TDA8262HN/C1,118 uniquely combines ZIF conversion, integrated XTOUT clock distribution, 20 dB LNA attenuation, and four-device I²C addressing - enabling compact, low-cost, dual-channel satellite receivers with minimal external components.

FAQ
What is the operating supply voltage range for the TDA8262HN/C1,118?
The TDA8262HN/C1,118 operates from 3.15 V to 3.45 V (typ. 3.3 V) on all supply pins (VCC(RF), VCC(VCO), VCC(PLL), VCC(BB), VCC(DIG)). Absolute maximum is +3.6 V. Exceeding 3.45 V risks violating specification limits and may impact phase noise or AGC linearity. The IC does not support 5 V core operation - only the I²C bus (SCL/SDA/AS) tolerates 5 V inputs.
How does the TDA8262HN/C1,118 handle strong input signals above −15 dBm?
The TDA8262HN/C1,118 handles strong input signals up to 0 dBm using its configurable 20 dB RF attenuation mode, activated by setting the RFATT bit. In this mode, the LNA operates at −8 dB gain and the loop-through path is also attenuated by 20 dB. This prevents saturation while maintaining signal integrity for demodulators sensitive to overload.
Can the TDA8262HN/C1,118 drive two independent demodulators simultaneously?
Yes - the TDA8262HN/C1,118 integrates an RF loop-through (pin RFOUT) that provides a buffered copy of the RFIN signal. When paired with a second TDA8262HN/C1,118 (using unique I²C address set via AS pin), it enables true dual-channel "watch-and-record" functionality without external splitters or amplifiers - reducing insertion loss and cost.
What is the purpose of the XTOUT pin on the TDA8262HN/C1,118?
The XTOUT pin on the TDA8262HN/C1,118 outputs a buffered 16 MHz clock derived from the internal crystal oscillator. This signal directly drives the crystal input of companion demodulator ICs (e.g., TDA10086), eliminating the need for a second crystal and associated load capacitors - simplifying layout and reducing BOM count in satellite receiver designs.
Does the TDA8262HN/C1,118 support DVB-S2 8PSK modulation?
Yes - the TDA8262HN/C1,118 supports DVB-S2 8PSK via its wide 950–2175 MHz tuning range, programmable 5–36 MHz baseband filters, and high linearity (IIP3 = +6 dBm). Its 45 MBd symbol rate capability, low quadrature error (≤5°), and precise AGC control meet DVB-S2 Annex A requirements for adaptive coding and modulation schemes.
