Product details
Overview
TDA18273HN/C1,551 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/C1,551 datasheet, TDA18273HN/C1,551 pinout, TDA18273HN/C1,551 application, or TDA18273HN/C1,551 equivalent, this device is selected for high-immunity RF front-end designs requiring multistandard support, fast tuning, self-synchronized AGC, and crystal oscillator buffering in compact set-top boxes and digital TVs.
Technical Context
The TDA18273HN/C1,551 implements a fractional-N (FRAC-N) PLL with LC-VCO and integrated loop filter for precise local oscillator synthesis across 42–870 MHz RF input. Its architecture includes band-split RF filtering, IR mixer, and five-stage AGC with VSYNC synchronization mode to align gain control to vertical sync pulses.
It features fully integrated oscillators, a 16 MHz crystal oscillator output buffer, power level detector (PLD), and temperature sensor accessible via I²C-bus - all within a single-chip solution that replaces discrete tuner modules and external IF filters.

| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX3542ETJ+T | Higher noise figure (4.8 dB typ), supports only DVB-T/C (no DVB-T2/C2), requires external SAW filter | Limited to legacy digital TV systems; not suitable for DVB-T2 rollouts or hybrid analog/digital deployments | Select when cost-sensitive legacy DVB-T/C STBs require second-source availability without T2/C2 roadmap |
| SI2151-A10-GM | Lower RF range (42–1002 MHz), integrated DVB-T2 demodulator, no analog TV support, different pinout and I²C register map | System-on-chip approach with embedded demodulator - eliminates external demodulator but increases firmware coupling | Select for new DVB-T2-only designs where SoC integration reduces component count and simplifies validation |
Compared with MAX3542ETJ+T and SI2151-A10-GM, the TDA18273HN/C1,551 uniquely balances analog/digital hybrid operation, full DVB-T2/C2 readiness, and external demodulator flexibility - making it optimal for transitional broadcast hardware requiring long-term standard support and minimal redesign risk.

FAQ
What RF standards does the TDA18273HN/C1,551 support?
The TDA18273HN/C1,551 supports all major analog TV standards (PAL, SECAM, NTSC) and digital standards including DVB-T, DVB-T2, DVB-C, and DVB-C2. Its 42–870 MHz RF input range and programmable channel bandwidths (1.7–10 MHz) enable seamless operation across global terrestrial and cable broadcast systems without hardware modification. The TDA18273HN/C1,551 is explicitly validated for DVB-T2 and DVB-C2 readiness per NXP documentation.
Does the TDA18273HN/C1,551 require external SAW filters?
No, the TDA18273HN/C1,551 integrates full IF selectivity internally, eliminating the need for external SAW filters. This is confirmed in its "Features and benefits" section and verified in the block diagram showing on-die IF filters. The integration reduces bill-of-materials cost, PCB footprint, and calibration effort while maintaining channel selectivity across all supported bandwidths.
What is the function of the VSYNC pin on the TDA18273HN/C1,551?
The VSYNC pin on the TDA18273HN/C1,551 enables self-synchronized AGC mode, where automatic gain control updates are timed to vertical synchronization pulses from the incoming video signal. This prevents gain fluctuations during active video lines and stabilizes signal levels in analog and digital TV reception. The TDA18273HN/C1,551 uses this feature to maintain consistent demodulator input amplitude without external timing circuitry.
What package type is used for the TDA18273HN/C1,551?
The TDA18273HN/C1,551 uses the HVQFN40 package (SOT618-1), a 6 × 6 × 0.85 mm thermally enhanced very thin quad flat no-lead package with 40 terminals. This package is specified in Table 2 of the NXP short data sheet and supports high-density layout and efficient thermal dissipation in consumer TV and STB applications.
Is the TDA18273HN/C1,551 RoHS compliant?
Yes, the TDA18273HN/C1,551 is RoHS compliant, as explicitly stated in the "Features and benefits" section of the NXP short data sheet. This compliance applies to the commercial-grade version supplied under ordering code TDA18273HN/C1,551 and meets EU Directive 2011/65/EU requirements for hazardous substance restrictions.
