CX24123-11Z,518 Application Field and Working Principle

Introduction

The CX24123-11Z,518 is a Wide Band, digitally modulated CMOS TV Tuner chip, having a dual-channel (VHF/UHF) analog and digital television receiver. It is suitable for use with the analogue TV-Standards PAL, SECAM and NTSC, as well as digital TV standards, DVB-T (Digital Video Broadcasting – Terrestrial) and ISDB-T (Integrated Services Digital Broadcasting – Terrestrial).

Application Field

CX24123-11Z,518 is ideal for use in devices such as Smart- TVs, digital video receivers (including satellite, terrestrial, IP and cable), A/V media players, digital TVs, digital video recorders, digital audio/video devices and other applications requiring Analog/Digital TV tuner functions.

Working Principle

The CX24123-11Z,518 incorporates a dual-channel analog and digital TV tuner which provides PLL Frequency Synthesizer, fully integrated mixing, low noise amplifiers, programmable gain amplifiers, AGC, demodulators, and an ADC to enable digital video signal demodulation and processing. Furthermore, it includes an Embedded Video Decoder, Digital Filter Bank, Slicer and Control algorithms which allows an Automatic Channel Search and Automatic Picture set-up to be implemented in a very simple and cost-effective solution.

The CX24123-11Z,518 also provides a digital input interface, allowing direct connection and signal reception from digital sources such as satellite, terrestrial and cable. An onboard Digital signal processor (DSP) enables flexible decoding of digital signals, powerful signal processing (noise reduction, de-scrambling, de-multiplexing, encoding and other image correction functions) and audio processing (mixing, equalizing, bass expansion etc).

Conclusion

The CX24123-11Z,518 chip is an ideal solution for providing low-cost, high-performance Linear - Video Processing in a variety of applications. The wide-band coverage and onboard functions make it suitable for receiving both analogue and digital TV signals and decoding them into high-quality video and audio signals, which can then be further processed by the Digital Signal Processor or external encoders and decoders.
