TDA18286HN/C1K

Introduction

TDA18286HN/C1K is a single chip RF tuner IC developed by NXP. It offers excellent performance, high quality and low cost solution for DVB-T and DVB-H digital terrestrial broadcasting applications. The IC integrates tuner, analog IF demodulator, IF selection filter, RSSI, audio noise cancelling and digital audio filter functions in a single chip with low power consumption. The core of the chip is a high-performance synthesis architecture with low power consumption.

Application Field

TDA18286HN/C1K is mainly used in the DVB-T and DVB-H digital terrestrial broadcasting applications. The coverage of the IC covers the full range from VHF to UHF, with a center frequency of 55MHz to 868MHz. The 1.4MHz IF frequency selectivity is provided for demodulation. In addition, the IC can be used in terrestrial digital cable broadcasting, CATV digital terrestrial broadcasting, and data broadcasting.

Working Principle

The TDA18286HN/C1K is a single chip RF tuner IC that consists of an integrated synthesizer, tuner and digital demodulator. It is used in conjunction with a host processor, digital signal processing system and memory to build a complete DVB-T or DVB-H digital terrestrial broadcasting system. The core of chip is a high-performance synthesis architecture and various functions are integrated in a single chip. The synthesis architecture supports wide frequency range from VHF to UHF, up to 868MHz.

Analog signals from the antenna are received and amplified by the tuner and passed on to the synthesizer and IF demodulator. The synthesizer generates the signal required for the tuner, and the IF demodulator demodulates the signal from the tuner. The demodulated signal is then passed on to the signal processing system for decoding. The remaining functions such as IF selectivity, RSSI, audio noise cancelling, digital audio filtering and power control are handled by the DVB signal.

Conclusion

In summary, the TDA18286HN/C1K is a single chip RF tuner IC developed by NXP, mainly used in the DVB-T and DVB-H digital terrestrial broadcasting applications. The core of the chip is high-performance synthesis architecture with low power consumption. It offers excellent performance, high quality and low cost solution for digital terrestrial broadcasting applications.
