PLL PROGRAMMING
The on-chip PLL in the ’DAC26 can be used to generate sampling clocks from a wide range of MCLK’s available in a system.
The PLL works by generating oversampled clocks with respect to Fsref (44.1 kHz or 48 kHz). Frequency division generates
all other internal clocks. The table below gives a sample programming for PLL registers for some standard MCLK’s when
PLL is required. Whenever the MCLK is of the form of N x 128 x Fsref (N=2,3
,17), PLL is not required.
