TS4962 3W Filter-free Class D Audio Power Amplifier With Active Low Standby Mode

Stationary - MOPLL & Silicon Tuner TUA6020 2 Band TV Tuner Mixer-Oscillator-PLL with balanced IF-Amplifier. The TUA6020 device integrates a digitally programmable Phase Locked Loop (PLL) with a mixer-oscillator block that includes two balanced mixers and oscillators suitable for use in TV and VCR tuners. The PLL block features four selectable chip addresses.

The PLL, equipped with a 4 MHz quartz crystal, enables precise frequency setting of the tuner oscillator up to 1024 MHz in increments of 31.25, 50, 62.5, or 166.7 kHz. The tuning process is managed by a microprocessor via an I2C bus. The device includes three output ports, and a flag is activated when the loop is locked, which can be read by the processor through the I2C bus. This device is produced by Infineon Technologies Corporation.

The TUA6020 is a sophisticated component designed for high-performance television and video cassette recorder applications. Its architecture includes a digitally controlled PLL that ensures accurate frequency tuning, essential for receiving broadcast signals effectively. The inclusion of balanced mixers enhances the linearity and reduces noise, resulting in improved signal quality.

The PLL's ability to operate with a 4 MHz quartz crystal allows for fine-tuning capabilities across a wide frequency range, making it adaptable for various broadcasting standards. The programmable nature of the PLL, controlled via a microprocessor, provides flexibility in tuning operations, allowing for dynamic adjustments based on the specific requirements of the incoming signals.

The integration of the I2C bus facilitates communication between the TUA6020 and the microprocessor, enabling efficient control and monitoring of the tuner operation. The three output ports provide access to essential status indicators and processed signals, enhancing the overall functionality of the tuning system. The loop lock flag serves as a critical feedback mechanism, ensuring that the system only operates when a stable signal is detected, thus optimizing performance and reliability.

Overall, the TUA6020 represents a robust solution for modern television and video applications, combining advanced tuning technology with user-friendly programmability.Stationary - MOPLL & Silicon Tuner TUA6020 2 Band TV Tuner Mixer-Oscillator-PLL with balanced IF-Amplifier The TUA6020 device combines a digitally programmable Phase locked loop (PLL), with a mixer-oscillator block including two balanced mixers and oscilla- tors for use in TV and VCR Tuners The PLL block with four selectable chip addresses forms a digitally programma- ble Phase locked loop With a 4 MHz quartz crystal, the PLL permits precise set- ting of the frequency of the Tuner Oscillator up to 1024 MHz in increments of 31. 25, 50, 62. 5 or 166. 7 kHz.
