This architecture achieves excellent dynamic performance of 106 dB SNR and improved clock jitter tolerance. The device supports sampling frequencies from 5 kHz to 200 kHz and accepts industry-standard audio data formats including I2S and 16-bit right-justified. Hardware control mode provides simple interface without register programming. The PCM1754 is pin-compatible with the PCM1748, PCM1742, and PCM1741 except for pin 5, enabling easy upgrades in existing designs.","working_principle":"The PCM1754DBQR operates using an enhanced multilevel delta-sigma architecture. The digital input data is first processed by a 4x or 8x oversampling digital interpolation filter that increases the sample rate and attenuates out-of-band quantization noise. The oversampled data then passes to a 4th-order delta-sigma modulator with 8-level amplitude quantization, which shapes quantization noise to higher frequencies. The resulting 1-bit\/8-level data stream drives an internal analog low-pass filter that reconstructs the continuous audio waveform. The 24-bit resolution provides theoretical dynamic range exceeding 144 dB, while the enhanced architecture delivers practical 106 dB performance. The device supports multiple system clock frequencies (128fS to 1152fS) with auto-detection for flexible clock design.","pin_description":"
