Electrical Characteristics
Note 4: In power down mode, set DATA, CLK and LE pins to 0 V (GND).
Note 5: The reference frequency must also be programmed using the OSC_FREQ control bit. For other reference frequencies, please contact National
Semiconductor.
Note 6: For other frequency ranges, please contact National Semiconductor.
Note 7: Lock time is defined as the time difference between the beginning of the frequency transition and the point at which the frequency remains within +/- 1 kHz
of the final frequency.
Note 8: Frequencies other that the default value can be programmed using Words R4 and R5. See Programming Description for details.
