To ensure the highest quality conversion of PWM signals, the CS44800 is capable of operating from a
fundamental mode or 3
to 54 MHz. If XTI is being directly driven by a clock signal, XTO can be left floating or tied to ground
through a pull-down resistor and the internal oscillator should be powered down using the PDN_XTAL bit
in register 02h.
