Notes

*1. Differential (+ or

–) current output is equivalent to a differential (+ or –) voltage source in series with an 806

 11%

resistor. The differential (+ or

–) voltage source has a peak-to-peak output range of 0.924 x AVCC = 3.05V and an

output offset of AVCC / 2 = 1.65V.

*2. With internal DVDD, maximum MCLK frequency is 50MHz (DVCC = +1.8V), or up to 100MHz (DVCC = +3.3V) using

an external +1.3V DVDD supply.

*3. Synchronous MCLK at 128 x FSR is also supported.
