PCM5102A DAC Digital to Analog Converter

Product Introduction:

The PCM5102 chip integrates a stereo analog-to-digital converter (DAC) to achieve excellent dynamic performance and improve resistance to clock jitter. With DirectPathTM charge pump technology, the PCM510xA device provides a 2.1VRMS central ground output (designers do not need to connect a DC isolation capacitor on the output) and an external mute circuit traditionally associated with single power line drivers. Integrated with soft mute and hardware mute, achieving 120dB mute signal-to-noise ratio (SNR). Each pin of the integrated circuit driver supports loads as low as 1K ohms, surpassing all other charge pump based circuit drivers in terms of performance. The device integrates a high-performance integrated audio phase-locked loop (PPL) with a BCK reference, which can generate SCK internally, eliminating the need for a system clock (usually referred to as the main clock), thus achieving a 3-wire I2S connection and reducing system electromagnetic interference (EMI). The intelligent clock error and PowerSenseq undervoltage protection adopt a double-layer system, which can eliminate clicking and clicking sounds. Compared to many traditional switched capacitor DAC architectures, it can control out of band noise at a lower level of 20dB, thereby reducing EMI and aliasing in downstream amplifiers/ADCs. At that time, there was an error in the clock and power system, and the device automatically attenuated the data and activated the analog mute circuit.
