Product details
Overview
TDA18219HN/C1,551 from NXP Semiconductors is a fully integrated silicon tuner IC for terrestrial and cable digital TV reception, supporting DVB-T/T2, ISDB-T, DTMB, ATSC, and DVB-C standards. It delivers a low intermediate frequency (LIF) output (3–5 MHz) with 1.7–10 MHz configurable channel bandwidths, operates from a single 3.3 V supply, and achieves 5.0 dB typical noise figure across 42–870 MHz RF input range.
For engineers reviewing the TDA18219HN/C1,551 datasheet, TDA18219HN/C1,551 pinout, TDA18219HN/C1,551 application, or TDA18219HN/C1,551 equivalent, this page provides verified technical context, validated pin functions, confirmed LIF architecture details, real-world TV system integration constraints, and direct alternative part comparisons for tuner design-in decisions.
Technical Context
The TDA18219HN/C1,551 implements a fractional-N (FRAC-N) PLL-based local oscillator with LC-VCO and integrated loop filter, enabling precise RF-to-LIF downconversion without external SAW filters. Its alignment-free architecture eliminates manual tuning during production.
It integrates five-stage AGC with dedicated AGCK logic, crystal oscillator buffer (16 MHz), I²C-bus interface compatible with 3.3 V microcontrollers, and Loop-Through (LT) functionality for multi-tuner cascading - all within a thermally enhanced HVQFN40 package.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| RF Frequency Range | 42–870 MHz: covers full VHF/UHF terrestrial and cable TV bands without external band-switching circuitry. |
| Noise Figure (NFtun) | Typ. 5.0 dB at max gain: ensures high sensitivity for weak-signal reception in urban multipath environments. |
| LIF Output Center Frequency | 3–5 MHz: enables use of low-cost, high-selectivity IF filters and simplifies demodulator interface design. |
| Channel Bandwidths | 1.7 / 6 / 7 / 8 / 10 MHz: supports global DTV standards including 6 MHz ATSC, 7/8 MHz DVB-T, and 1.7 MHz DTMB. |
| Image Rejection (αimage) | Min. 55 dB: suppresses adjacent-channel interference critical for co-channel rejection in dense RF environments. |
| 1 dB Input Compression (ICP1dB) | 124 dBµV: maintains linearity under strong off-channel signals, preventing desensitization in mixed-signal front-ends. |
| Phase Jitter (1 kHz–4 MHz) | Typ. 0.5°: meets stringent symbol clock stability requirements for QAM-256 and OFDM demodulation. |
Pinout & Package
HVQFN40 (SOT618-1) package: 6 × 6 × 0.85 mm body, thermal-enhanced exposed pad, no leads, 40 terminals - optimized for compact TV set-top box and integrated digital TV PCB layouts.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| RFIN | RF Input | Single-ended 75 Ω input port accepting full 42–870 MHz spectrum; internal LNA enables direct antenna connection. |
| IFP / IFN | Differential LIF Output | Low-IF differential pair (3–5 MHz center) drives channel demodulator with minimal external filtering required. |
| SCL / SDA | I²C Bus Interface | 3.3 V-compatible serial control lines for register configuration, tuning, and status readback without level-shifting. |
| XTALP / XTALN | Crytal Oscillator Input | Differential crystal connection for 16 MHz reference; internal buffer supports single-crystal system architecture. |
| VTUNE | VCO Tuning Voltage | Analog voltage output controlling LC-VCO frequency; used for calibration and fine-tuning during production test. |
| IRQ | Interrupt Request | Open-drain active-low signal indicating tuning completion, AGC lock, or error condition to host MCU. |
| LT Enable | Loop-Through Control | Enables pass-through of RF signal to downstream tuner in multi-tuner architectures (e.g., PVR dual-tuner systems). |
Key Features
| Feature | Design Value |
|---|---|
| Fully integrated IF selectivity | Eliminates external SAW filters - reduces BOM count by ≥3 components and PCB area by >15 mm² per tuner stage. |
| Alignment-free architecture | Removes factory calibration steps - cuts manufacturing test time by ~12 seconds per unit and eliminates trimmer components. |
| Integrated wideband gain control | Five-stage AGC with AGCK logic adapts to dynamic signal strength across DVB-T2 and ATSC 3.0 channel profiles. |
| Crystal oscillator output buffer | 16 MHz buffered clock output allows shared crystal between tuner and demodulator - lowers system cost and jitter coupling. |
| 5 ms tuning time | Meets fast channel-change requirement (<100 ms total) for consumer TV UX without perceptible delay. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar silicon tuner applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX3542ETJ+T | Supports DVB-T/T2 only; requires external 27 MHz crystal; no Loop-Through; 6.5 dB NF (vs. 5.0 dB typ.) | Lacks DTMB/ATSC support; not suitable for China or North American cable deployments. | Select when targeting DVB-only markets with legacy crystal sourcing and no LT requirement. |
