Application Information (Continued)
TLW12340 – 43
FIGURE 5 PLL Reference Spurs
The reference spurious level is k b66 dBc due to the loop
filter attenuation and the low spurious noise level of the
LMX1511
TLW12340 – 45
The phase noise level at 3 kHz offset is b65 dBcHz
TLW12340 – 44
FIGURE 7 PLL Phase Noise
150 Hz Offset
The phase noise level at 150 Hz offset is b755 dBcHz
TLW12340 – 42
FIGURE 8 Frequency Jump Lock Time
Of concern in any PLL loop filter design is the time it takes
to lock in to a new frequency when switching channels
Fig-
ure 8 shows the switching waveforms for a frequency jump
of 857 MHz – 915 MHz By narrowing the frequency span of
the HP53310A Modulation Domain Analyzer enables evalu-
ation of the frequency lock time to within g1 kHz The lock
time is seen to be k 16 ms for a frequency jump of 58 MHz
