NOTE:
1. Mid is defined as a voltage level between 1.0 V and 1.8 V for 3 level input functionality. Low is below 0.8 V. High is above 2.0 V.
2. 3V66_1/VCH output frequency is set by the I2C.
3. Frequency of the 48 MHz outputs must be +167 ppm to match USB default.
4. Rref output min = 14.316 MHz, nominal = 14.31818, max = 14.32 MHz.
5. Tclk is a test clock over-driven on the XTAL_In input during test mode.
