ESD CAUTION
ESD (electrostatic discharge) sensitive device. Electrostatic charges as high as 4000 V readily accumulate on the
human body and test equipment and can discharge without detection. Although this product features
proprietary ESD protection circuitry, permanent damage may occur on devices subjected to high energy
electrostatic discharges. Therefore, proper ESD precautions are recommended to avoid performance
degradation or loss of functionality.

PLL divisor to the chip should be an odd integer; Chip divide ratio = Input N + offset of 1.
The VCO range and charge pump current settings are preliminary and may need slight adjustments.
