TEA6848HL/V3S,518

TEA6848HL/V3S is a multi-branch demodulator for dual-channel FM/AM stereo radio. It is a monolithic integrated circuit that reduces the number of external components and features a low power consumption. TEA6848HL/V3S belongs to the family of RF Receivers.

Applications

The TEA6848HL/V3S can be used in several applications. It is mainly used in car radios, HiFi receivers and home theater applications. It is also widely used in electronic equipment that require stereo reception, such as portable media players, portable gaming consoles, GPS navigations systems and boom boxes.

Features

The TEA6848HL/V3S offers several features that make it an ideal solution for many applications. It supports both analog and digital receivers, with analog receiver supporting FM/AM tuning and digital tuning supporting Digital Audio Broadcasting (DAB). It also features automatic gain control (AGC), low-IF processing with stereo decoder and quadrature demodulation.

In addition, the TEA6848HL/V3S has an integrated DC/DC converter to power the external components and supports both positive and negative supply voltages. It also features a muting function to reduce noise level and protect the audio output. The integrated voltage regulator also provides low transient consumption, resulting in improved audio quality.

Working Principle

TEA6848HL/V3S uses an integrated low noise amplifier to receive the incoming signals. The signal is then processed by the analog-to-digital converter and processed to identify the type of modulation used. The demodulated signal is then passed through a multistage IF filter for further amplification. Finally, the signal is processed by the stereo decoder to reconstruct the audio signals.

The stereo decoder is used to detect the stereo signals and separate the left and right channels. It also has an integrated equalizer to adjust the gain of each channel and balance the audio response. The analog-to-digital converter also helps to reduce distortion and noise levels related to the analog signal.

Conclusion

The TEA6848HL/V3S is an ideal solution for a wide range of applications that require stereo reception. It features an integrated DC/DC converter, low-IF processing and stereo decoder, making it an excellent choice for car radio and HiFi receivers. In addition, it features low power consumption and high performance, making it suitable for a variety of portable devices.
