Input clock
SELCLK33
In STA529 the oversampling clock comes from MCLK33 or from pin XTI. The selection is
done by applying the appropriate voltage to pin SELCLK33. If SELCLK33 is logical 1 then
MCLK33 is selected, otherwise XTI is selected.
If an external crystal is used, SELCLK33 pin must be connected to GND and the suggested
circuit shown below should be used.
