QUANTIZATION NOISE SPECTRUM

(128× OVERSAMPLING)
Figure 37. Quantization-Noise Spectrum
Figure 38 illustrates the simulated jitter sensitivity of the PCM1602A. To achieve best performance, the system
clock jitter should be less than 300 picoseconds. This is easily achieved using a quality clock generation IC, like
the PLL170x from Texas Instruments.
