SYSTEM CLOCK AND RESET FUNCTIONS
System Clock Input
The PCM1753/54/55 requires a system clock for operating the digital interpolation filters and multilevel
delta-sigma modulators. The system clock is applied at the SCK input (pin 16). Table 1 shows examples of
system clock frequencies for common audio sampling rates.
Figure 19 shows the timing requirements for the system clock input. For optimal performance, it is important
to use a clock source with low phase-jitter and noise. TI’s PLL170x family of multiclock generators is an excellent
choice for providing the PCM1753/54/55 system clock.
