The PCM1774RGPR is a double buffered Sigma-Delta modulator made specifically for consumer audio applications. It contains a 24-bit stereo sigma-delta audio ADC with an adjustable sampling rate between 8 kHz to 192 kHz and a 32-bit Delta Sigma DAC allowing the user to output a maximum of 24 bits of resolution from the system. This device is really advantageous for consumer audio applications because of its low supply current, low power dissipation, versatile sample-rate controls, and its stereo headphone/line out driver. Despite its mainly consumer application, this device can also be used in a wide variety of special-purpose field.

PCM1774RGPR Application Field

The PCM1774RGPR is designed for consumer audio applications when needing to record or reproduce digital audio. It is used for various types such as recording devices, set-top boxes, digital cameras, portable audio and gaming consoles, car audio systems, and televisions. Applications include music player, amplifier, and speaker systems. It is also used for a variety of special purpose applications such as medical imaging, vibration and sound analysis, automotive and security systems, and precision recording.

The PCM1774RGPR can also be used in portable audio systems, such as the iPod, allowing users to record and output high-quality audio. Furthermore, can also be integrated into game consoles, such as the Sony PlayStation3, allowing users to experience high-definition audio through their consoles. Additionally, because of its low power consumption, lightweight size and advanced features, the PCM1774RGPR is also suitable for low-cost systems such as digital cameras, set-top boxes, portable audio devices, and car audio systems.

PCM1774RGPR Working Principle

The PCM1774RGPR utilizes a modified Sigma Delta modulator to convert digital audio signal into analog signal. The Sigma Delta modulator is a type of digital audio converter, which processes analog signal and converts them into a digital stream. Its basic operating principle relies on the idea that, given a certain level of control, the signal is converted and moved into a range of accepted, low-noise signal levels. The signal is then converted from analog to digital using the Sigma Delta modulator and the signal is then sent to the output of the PCM1774RGPR.

The PCM1774RGPR also utilizes hybrid frequency modulation, meaning that both frequencies, high and low, are simultaneously modulated in order to reduce the aliasing distortion present in other sigma-delta techniques. As this device is designed for audio applications, it is important to reduce the distortions or artifacts that occur due to the conversion and output process. For the DAC output, the device utilizes a 3rd order noise shaper filter to reduce the amount of noise and distortion associated with the audio signal. This filter seeks to preserve the integrity of the audio signal while at the same time improving the signal to noise ratio.

In addition, the PCM1774RGPR incorporates a programmable Digital Low Pass Filter (DLPF) which allows programmers to optimize the device performance based on their application requirements. Furthermore, the device offers multiple input options, allowing versatility when integrating the solution. The inputs include Line/Condenser, Digital Microphone (DMIC) and analog inputs. This makes it possible for the PCM1774RGPR to be integrated into a wide variety of applications, including audio and special-purpose applications that require the highest precision.

Conclusion

The PCM1774RGPR is a double-buffered sigma-delta modulator designed specifically for consumer audio applications. However, its versatility allows it to be used in a variety of special-purpose applications as well. It employs hybrid modulation in order to reduce the amount of aliasing distortion, and it also utilizes a 3rd order noise shaper filter to reduce noise and preserve the integrity of the audio signal. Additionally, it is able to integrate multiple input options and can be programmable, allowing it to be optimized for different applications. Therefore, the PCM1774RGPR is an excellent solution for applications needing high-resolution audio recording and playback.
