LMX2594 Multiple PLL Reference Design(TIDA-01346)

The TIDA-01346 design uses two LMX2594 synthesizers in combination to produce lower noise than is possible with just one. By combining the output of two synthesizers that are in phase, a theoretical 3 dB phase noise benefit is possible due to the output power being 6 dB higher while the noise power is only 3 dB higher. The LMX2594 is an ideal synthesizer for this application as it has a SYNC feature that allows it to have deterministic and repeatable phase as well as a programmable phase that can be used to correct for any phase error due to trace mismatches or any other factors.
