Product details
Overview
TDA18211HD/C2,557 from NXP Semiconductors is a single-chip silicon tuner IC for DVB-T terrestrial TV reception, integrating RF tracking filters, IF selectivity, and a 16 MHz crystal oscillator. It delivers low-IF output (6/7/8 MHz channel bandwidths), achieves 65 dB image rejection, consumes 780 mW at 3.3 V, and supports dual-tuner synchronization via MASTERSYNC/FREEZE signals in STB applications.
For engineers reviewing the TDA18211HD/C2,557 datasheet, TDA18211HD/C2,557 pinout, TDA18211HD/C2,557 application, or TDA18211HD/C2,557 equivalent, key selection criteria include RF input range (174–864 MHz), integrated thermal sensing, I²C interface compatibility with 3.3 V/5 V microcontrollers, three standby modes, and crystal oscillator buffer output for multi-tuner clock distribution.
Technical Context
The TDA18211HD/C2,557 implements a direct-conversion architecture with RF-to-low-IF downconversion using an image-rejection mixer and integrated polyphase filtering. Its dual-synthesizer system includes a main LO synthesizer (tuned via VT_COARSE/VT_FINE) and a calibration synthesizer (controlled by CP_CAL/VT_CAL), enabling on-chip RF tracking filter and image rejection calibration without external components.
It supports master/slave dual-tuner operation via XTOUT_MS voltage selection (0 V to 0.1VCC = master; 0.4VCC to 0.6VCC = slave), provides loop-through (LT) and slave-tuner output (STO) with automatic gain compensation, and uses internal regulators decoupled via CAPREG18/CAPREG28/CAPREGVCO/CAPFILTVCO/CAPREGFILTRF.

Equivalent & Alternatives
The following parts are listed as comparable options for similar DVB-T silicon tuner applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX2165ETJ+T | Requires external 26 MHz crystal; no integrated thermal sensor; IF output is 3.3 V CMOS, not differential sine. | Lacks native dual-tuner synchronization; needs external clock fanout buffer for multi-tuner systems. | Prefer when existing designs use 26 MHz infrastructure and require lower cost over thermal monitoring. |
| SI2151-A10-GM | Supports DVB-T/T2/ISDB-T; higher integration (integrated demodulator); 1.8 V core supply only. | Not pin-compatible; requires redesign of power delivery and interface logic for 1.8 V I/O. | Choose for next-gen T2 support and SoC-like integration, accepting layout rework and new qualification. |
Compared with MAX2165ETJ+T and SI2151-A10-GM, the TDA18211HD/C2,557 uniquely combines 16 MHz crystal integration, differential clock output for multi-tuner sync, and on-die thermal sensing-enabling compact, thermally robust DVB-T STBs without external clock buffers or thermal diodes.

FAQ
What is the recommended crystal for TDA18211HD/C2,557 and how is it connected?
The TDA18211HD/C2,557 requires a 16 MHz fundamental-mode quartz crystal rated for ≥100 µW drive level. Recommended parts include NDK NX5032, Siward SX-5032, TXC 9C series, and Chungho Elcom HC49/S. It connects directly between XTALP (pin 26) and XTALN (pin 27), with a typical 5.6 pF shunt capacitor across the crystal per the datasheet layout guidelines. The TDA18211HD/C2,557 provides internal negative impedance in master mode.
How does the TDA18211HD/C2,557 support dual-tuner configurations?
The TDA18211HD/C2,557 supports dual-tuner operation via hardware-configurable master/slave modes selected by voltage on XTOUT_MS (pin 29). In master mode (0–0.1VCC), it drives XTOUTP/XTOUTN with a 16 MHz differential clock; in slave mode (0.4–0.6VCC), it accepts that clock on XTALP/XTALN. MASTERSYNC (pin 19) and FREEZE (pin 28) coordinate calibration and LO phase alignment between tuners, ensuring coherent signal processing.
What are the three standby modes of the TDA18211HD/C2,557 and how are they controlled?
The TDA18211HD/C2,557 offers three standby modes controlled via SM, SM_LT, and SM_XT bits in EP3 (subaddress 05h): Normal mode (SM=0), Standby with crystal/loop-through/STO active (SM=1, SM_LT=0, SM_XT=0), Standby with only crystal active (SM=1, SM_LT=1, SM_XT=0), and Device-off (SM=1, SM_LT=1, SM_XT=1). Device-off achieves lowest power; all modes retain I²C functionality for remote wake-up.
Does the TDA18211HD/C2,557 require external SAW filters for IF selectivity?
No, the TDA18211HD/C2,557 integrates full IF selectivity for 6 MHz, 7 MHz, and 8 MHz channel bandwidths using on-die low-pass and polyphase filters. This eliminates the need for external SAW filters, reducing bill-of-materials cost, PCB area, and assembly complexity while maintaining >53 dB image rejection and meeting ETSI EN 300 744 spectral mask requirements.
What is the function of the VSYNC pin (pin 51) on the TDA18211HD/C2,557?
The VSYNC pin (51) on the TDA18211HD/C2,557 provides vertical synchronization input for analog TV standards (NTSC/PAL). When used in digital-only DVB-T applications, this pin must be connected to ground. Its presence enables hybrid receiver designs where the same tuner feeds both digital demodulators and legacy analog video processors, simplifying migration paths in multi-standard TVs.
