NXP Semiconductors TDA18219HN/C1,518

Overview

TDA18219HN/C1,518 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 selectable 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/C1,518 datasheet, TDA18219HN/C1,518 pinout, TDA18219HN/C1,518 application, or TDA18219HN/C1,518 equivalent, key selection criteria include its integrated IF selectivity (eliminating external SAW filters), alignment-free architecture, 5 ms tuning time, crystal oscillator buffer for single-crystal designs, and I²C interface compatibility with 3.3 V microcontrollers.

Technical Context

The TDA18219HN/C1,518 implements a fractional-N (FRAC-N) PLL with LC-VCO and integrated loop filter to generate precise local oscillator signals across UHF/VHF bands. Its RF front-end includes a low-noise amplifier (LNA), RF AGC, and image-rejection mixer achieving ≥55 dB worst-case image rejection.

Baseband processing integrates programmable IF filters, wideband gain control, and temperature-compensated IF AGC. The device outputs differential LIF (IFP/IFN), provides loop-through (LT) capability, and features an on-die temperature sensor readable via I²C for thermal management.

FAQ

What digital TV standards does the TDA18219HN/C1,518 support?

The TDA18219HN/C1,518 supports DVB-T/T2, ISDB-T, DTMB, ATSC, and DVB-C standards. It is explicitly qualified for terrestrial and cable digital TV reception across all these formats, with RF coverage from 42 MHz to 870 MHz and configurable LIF center frequencies (3–5 MHz) and channel bandwidths (1.7–10 MHz) to match each standard's requirements. This multi-standard capability is confirmed in the official NXP short data sheet Rev. 6.

Does the TDA18219HN/C1,518 require external SAW filters?

No, the TDA18219HN/C1,518 does not require external SAW filters. Its fully integrated IF selectivity replaces them entirely, as stated in the "Features and benefits" section of the NXP datasheet. This integration reduces bill-of-materials count, eliminates filter matching, and avoids production calibration-directly enabling smaller, lower-cost tuner designs without compromising adjacent-channel rejection.

What is the tuning time specification for the TDA18219HN/C1,518?

The TDA18219HN/C1,518 has a specified tuning time of 5 ms, as documented in the NXP short data sheet Rev. 6. This value represents the time required to lock the FRAC-N PLL and stabilize the LIF output after a channel change command via I²C. It meets fast-switching requirements for interactive TV, PVR, and multi-tuner applications where sub-100 ms user-perceived latency is essential.

Can the TDA18219HN/C1,518 operate from a single 3.3 V supply?

Yes, the TDA18219HN/C1,518 operates from a single 3.3 V supply, with absolute maximum rating of +3.6 V and minimum operating voltage of −0.3 V per the limiting values table. All internal blocks-including LNA, mixer, VCO, IF filters, and I²C interface-are designed for 3.3 V operation, eliminating need for multiple supply rails or level shifters in system design.

What package type is used for the TDA18219HN/C1,518?

The TDA18219HN/C1,518 uses the HVQFN40 plastic thermal enhanced very thin quad flat package (SOT618-1), measuring 6 × 6 × 0.85 mm with 40 terminals. This RoHS-compliant package features exposed thermal pad for efficient heat dissipation and is optimized for high-density digital TV PCB layouts, as confirmed in Table 2 of the NXP ordering information section.
