1 If AVDD is below 2.8 V, distortion performance may be compromised.
The following values are to be used when the clock doubler is active:

24.576 26 MHz
1 The maximum sample rate that may be played with correct speed is CLKI/512.
The following values are to be used when the clock doubler is not active:

1 The maximum sample rate that may be decoded with correct speed is CLKI/512.
Note: With higher than typical voltages, VS1011 may operate with CLKI upto 30..32 MHz. However,
the chips are not qualiï¬ed for this kind of usage. If necessary, VLSI Solution Oy can qualify chips for
higher clock rates for quantity orders.
