TDA7521 General Description

1.1 Clock source and generation The master clock to operate the device is 768 ×Fs (High Frequency mode, HFM) or 384 ×Fs (Low Frequency mode, LFM). Fs=44.1KHz for CD applications. In either case, the clock is generated by TDA7522: an internal low-jitter Charge-Pump PLL (CPPLL) and a Finite State Mach.
