NXP Semiconductors TDA18219HN/C1,557

Overview

TDA18219HN/C1,557 from NXP Semiconductors is a single-chip 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-IF (LIF) output (3–5 MHz center frequency) 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/C1,557 datasheet, TDA18219HN/C1,557 pinout, TDA18219HN/C1,557 application, or TDA18219HN/C1,557 equivalent, key selection criteria include LIF architecture compatibility with demodulator interfaces, integrated IF selectivity eliminating external SAW filters, I²C-bus programmability for rapid tuning, and thermal-enhanced HVQFN40 packaging for high-density TV tuner modules.

Technical Context

The TDA18219HN/C1,557 implements a fully integrated fractional-N (FRAC-N) PLL-based local oscillator with LC-VCO and crystal oscillator buffer (16 MHz), enabling precise RF-to-LIF downconversion without alignment. Its architecture includes five-stage AGC with CAPRFAGC and VIFAGC control, integrated temperature sensor accessible via I²C, and loop-through (LT) functionality for multi-tuner systems.

It features on-die IF filtering with programmable bandwidths (1.7/6/7/8/10 MHz), image rejection ≥55 dB, phase jitter ≤0.7° (1 kHz–4 MHz), and 1 dB input compression point of 124 dBµV - all optimized for direct interface to DVB-T2 and ISDB-T channel demodulators in set-top boxes and integrated digital TVs.

FAQ

What digital TV standards does the TDA18219HN/C1,557 support?

The TDA18219HN/C1,557 supports DVB-T/T2, ISDB-T, DTMB, ATSC, and DVB-C standards. This full multi-standard coverage enables single-design reuse across European, Asian, North American, and Latin American broadcast markets without hardware changes. Each standard is supported natively within the IC's RF front-end and IF processing path, as confirmed in the NXP short data sheet Rev. 6.

Does the TDA18219HN/C1,557 require external SAW filters?

No, the TDA18219HN/C1,557 does not require external SAW filters due to its fully integrated IF selectivity. The on-die IF filters provide programmable bandwidths (1.7/6/7/8/10 MHz) and eliminate the need for off-chip filtering components, reducing bill-of-materials cost and PCB area. This feature is explicitly stated in the "Features and benefits" section of the official NXP datasheet.

What is the RF input frequency range of the TDA18219HN/C1,557?

The TDA18219HN/C1,557 accepts RF input from 42 MHz to 870 MHz, covering the full VHF and UHF bands used for terrestrial and cable digital TV broadcasting worldwide. This range is specified in Table 1 ("Quick reference data") of the NXP short data sheet, with no gaps or sub-band limitations.

How is the TDA18219HN/C1,557 powered, and what is its typical noise figure?

The TDA18219HN/C1,557 operates from a single 3.3 V supply, with limiting values allowing −0.3 V to +3.6 V. Its typical tuner noise figure is 5.0 dB under 75 Ω source impedance and maximum gain conditions, as measured across the full 42–870 MHz RF range per the NXP short data sheet Rev. 6.

What package type is used for the TDA18219HN/C1,557?

The TDA18219HN/C1,557 uses the HVQFN40 (SOT618-1) package: a thermally enhanced, leadless 6 × 6 × 0.85 mm quad flat package with 40 terminals. This package is documented in Table 2 ("Ordering information") of the NXP short data sheet and is optimized for high-density TV tuner PCB layouts with efficient thermal dissipation.
