PCM1702U Frequently Asked Questions (FAQ)
-
The recommended power-on sequence is to apply VCC first, followed by VREF, and then the analog and digital inputs. This ensures proper device operation and prevents damage.
-
The analog input filter should be designed to reject noise and aliasing. A 3rd-order Butterworth filter with a cutoff frequency of 40 kHz is recommended. The filter should also provide a gain of 1-2 dB to optimize the signal-to-noise ratio.
-
The recommended clock frequency is 256 fs (where fs is the sampling frequency). The clock jitter tolerance is ±50 ppm, and the clock amplitude should be between 2.5 V and 5 V.
-
The PCM1702U outputs 24-bit data in MSB-first, two's complement format. The data is output on the D0-D23 pins, with D0 being the MSB. The output data rate is equal to the sampling frequency.
-
The PCM1702U requires a solid ground plane and separate analog and digital ground planes. The analog and digital supplies should be decoupled with 10 μF and 100 nF capacitors, respectively. The layout should also minimize noise coupling between analog and digital signals.
