The maximum sample rate that may be decoded with correct speed is CLKI/512.
Note: With higher than typical voltages, VS1001k may operate with CLKI upto 30..32 MHz. However,
the chips are not qualified for this kind of usage. If necessary, VLSI Solution Oy can qualify chips for
higher clock rates for quantity orders.
