Operating Ratings indicate conditions for which the device is intended to be functional, but do not guarantee specific performance limits. For guaranteed specifications and conditions, see the Electrical Characteristics. The guaranteed specifications apply only for the conditions listed. Note 2: This device is a high performance RF integrated circuit with an ESD rating <2 kV. Handling and assembly of this device should only be done at ESD free workstations. Note 3: Typical Conditions are at a TA of 25˚C. Note 4: Icc current is measured with Clock, Data and LE pins connected to GND. OSCin and Fin pins are connected to Vcc. PWDN bit is program to 0. Icc current is the current into Vcc pin. Note 5: See FIN Sensitivity Test Setup. Note 6: See OSCIN Sensitivity Test Setup. Note 7: Charge Pump Magnitude is controlled by CPo_4X bit [R18]. Note 8: See Charge Pump Measurement Definition for detail on how these measurements are made. Note 9: Analog Lock Detect open drain output pin only can be pulled up to Vext that will not exceed 6.5V. Note 10: See Serial Input Data Timing. Note 11: Normalized Single-Side Band Phase Noise is defined as: LN(f) = L(f) − 20 log (FIN/Fφ), where L(f) is defined as the Single Side-Band Phase Noise. www.national.com 7 |
