I've trouble configuring the SSM2529. Fault description:
Playing a sine sweep and hearing multiple reflections of the Signal (see picture, sine at 8KHz),
also Signals cuts off at 15KHz.
I2S Signal 44,1 KHz, 32Bit
BCLK as source (44,1 kHz * 2 * 32), DPLL_NDIV=2 (*4), X = 2, R = 5, N=1, M=1
(PLLs are locked)
-chip is working even if DPLL_NDIV=1 (APPL input < 8 MHz)
-not all possible combination of PLL parameters are working, even if freq is listed in table 48 (MCLK ratio)
-Function of FSYS_DPLL(APLL_CTRL6)
-Function of Bit 0 (APLL operation mode) in APLL_CTRL5 REGISTER
Added original sine sweep and recorded one for comparisation.
Complete registerset SSM2529: (all other values are resetvalues)
