LMX2531LQ2570E EVALUATION BOARD OPERATING INSTRUCTIONS
Spurs (Internal Divide by 2 Enabled)
Spur at 200 kHz offset at a frequency of
1170.1 MHz is –90.1 dBc. Since this mode
uses the divide by 2 mode, the channel
spacing here is actually 100 kHz. The spur
at 100 kHz could be eliminated by doubling
the channel spacing before the divider.
The reason that the spur at 200 kHz is
shown is to illustrate theoretical 6 dB
impact of the divider.
Spur at 200 kHz offset for a frequency of
1285.1 MHz is -87.5 dBc.
Spur at 200 kHz offset for a frequency of
1395.1 MHz is -83.6 dBc.
