LMX2595 EVM Instructions - 19-GHz Wideband Low Noise
This Evaluation Module is for the LMX2595, which is the first PLL with integrated VCO in industry to get
fundamental VCO output up to 15 GHz. The industry leading PLL FOM is -236 dBc/Hz with 1/f of -129
dBc/Hz. This device supports JESD204B standard (it can generate or repeat the SYSREF signal) which
makes it ideal to clock high speed data converters. The integrated jitter from the EVM measurements is
less than 50 fs at 9 GHz carrier frequency. By providing a SYNC signal, the user can synchronize the
output phase across multiple LMX2595 devices. LMX2595 can also generate a frequency ramp which can
be demonstrated in this evaluation module. With an on-board oscillator, setup process only requires a
3.3V power supply and an included Reference Pro module (For SPI Programming interface). The software
is simple, with an intuitive and user friendly GUI.
