Product details
Overview
TDA18273HN/C1,557 from NXP Semiconductors is a hybrid silicon tuner IC for terrestrial and cable TV reception supporting both analog and digital standards including DVB-T2 and DVB-C2. It delivers a low-IF (LIF) output (3–5 MHz center frequency) with 1.7/6/7/8/10 MHz selectable channel bandwidths, operates from a single 3.3 V supply, and integrates full IF selectivity eliminating external SAW filters.
For engineers reviewing the TDA18273HN/C1,557 datasheet, TDA18273HN/C1,557 pinout, TDA18273HN/C1,557 application, or TDA18273HN/C1,557 equivalent, this device is critical for high-immunity, alignment-free TV tuner designs requiring fast tuning, integrated oscillators, and I²C-bus control compatible with 3.3 V microcontrollers.
Technical Context
The TDA18273HN/C1,557 implements a fractional-N (FRAC-N) PLL architecture with LC-VCO and crystal oscillator buffer (16 MHz), enabling precise RF synthesis across 42–870 MHz. Its RF front-end includes band-split filtering, LNA, and five-stage AGC with self-synchronization via VSYNC signal.
It features fully integrated IF filtering, power level detection (PLD), temperature sensing, and image rejection ≥57.5 dB - all within a single HVQFN40 package. The LIF architecture supports simultaneous analog TV demodulation and digital channel demodulation without external IF components.

Equivalent & Alternatives
The following parts are listed as comparable options for similar hybrid TV tuner applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX3543ETJ+ | Higher noise figure (4.8 dB typ), no integrated VSYNC sync mode, requires external 26 MHz crystal | Optimized for North American ATSC/QAM systems; lacks DVB-T2/C2 readiness | Select when legacy ATSC 1.0 or 8-VSB support is primary requirement and DVB-T2 is not needed |
| SI2151-A10-GM | Lower RF range (42–1002 MHz), no LIF output (direct RF sampling), higher power consumption (1.2 W vs. 0.85 W) | Targets software-defined radio (SDR) architectures with ADC-based demodulation; no analog TV support | Select for next-gen tuners using digital IF processing and where analog TV compatibility is not required |

FAQ
What RF frequency range does the TDA18273HN/C1,557 support?
The TDA18273HN/C1,557 supports an RF frequency range of 42–870 MHz, covering full VHF and UHF bands for terrestrial and cable TV applications. This range accommodates global analog standards (PAL, NTSC, SECAM) and digital standards including DVB-T, DVB-T2, DVB-C, and DVB-C2 as specified in the NXP short data sheet Rev. 3 (2011). The device maintains consistent noise figure and image rejection across this entire band.
Does the TDA18273HN/C1,557 require external SAW filters?
No, the TDA18273HN/C1,557 does not require external SAW filters due to its fully integrated IF selectivity. As stated in the "Features and benefits" section, this integration eliminates the need for external IF filtering components, reducing bill-of-materials count and PCB footprint. The internal IF filters support configurable channel bandwidths of 1.7, 6, 7, 8, and 10 MHz.
What is the supply voltage requirement for the TDA18273HN/C1,557?
The TDA18273HN/C1,557 operates from a single 3.3 V supply, with absolute maximum rating of +3.6 V and minimum of −0.3 V per the limiting values table. It is explicitly rated for 3.3 V microcontroller compatibility on its I²C interface (SCL/SDA), and all internal regulators and bias circuits are optimized for this rail - no auxiliary voltage rails are required.
How does the VSYNC feature function in the TDA18273HN/C1,557?
The VSYNC feature in the TDA18273HN/C1,557 enables self-AGC synchronization to the vertical synchronization signal of incoming analog video. When asserted, it aligns AGC updates to video field boundaries, preventing gain fluctuations during active video periods. This behavior is confirmed in the "Features and benefits" list and block diagram, where VSYNC connects directly to the AGC control logic.
Is the TDA18273HN/C1,557 RoHS compliant and what package does it use?
Yes, the TDA18273HN/C1,557 is RoHS compliant as explicitly stated in the "Features and benefits" section. It is packaged in HVQFN40 (SOT618-1): a 6 × 6 × 0.85 mm thermal-enhanced very thin quad flat no-lead package with 40 terminals, as documented in Table 2 of the ordering information section.
