Note 5:
RF PLL and VCO in PDC800 mode.
Note 6:
RF PLL and VCO in PDC1500 mode.
Note 7:
The reference frequency must also be programmed using the OSC_FREQ control bit. For other reference frequencies, please contact National
Semiconductor.
Note 8:
For other frequency ranges, please contact National Semiconductor.
Note 9:
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 10:
Lock time is defined as the time difference between the beginning of the frequency transition and the point at which the frequency remains within +/-3 kHz
of the final frequency.
Note 11:
All limits are guaranteed. All electrical characteristics having room temperature limits are tested during production with T
= 25 C or correlated using
Statistical Quality Control (SQC) methods. All hot and cold limits are guaranteed by correlating the electrical characteristics to process and temperature variations
and applying statistical process control.
