Notes

1. Differential (+ or

–) current output is equivalent to a differential (+ or –) voltage source in series with a 403

 11% resistor.

The differential (+ or

–) voltage source has a peak-to-peak output range of (0.867 x AVCC) & an output offset of (AVCC / 2).

2. With internal DVDD, maximum MCLK frequency is 50MHz (DVCC = +1.8V).

MCLK can be up to 100MHz (DVCC = +3.3V) using an external +1.3V

5% DVDD supply.

3. ES9028Q2M also supports synchronous MCLK at 128 x FSR.
