Product Overview

The LMX2594EVM from Texas Instruments is a 15GHz wideband RF synthesizer with phase synchronization & JESD204B evaluation module. LMX2594 is the first PLL with integrated VCO in industry to get fundamental VCO output up to 15GHz. The industry leading PLL FOM is -236dBc/Hz with 1/f of -129dBc/Hz. This device supports JESD204B standard which makes it ideal to clock high speed data converters. The integrated jitter from the EVM measurements is less than 50fs at 9GHz carrier frequency. By providing a SYNC signal, the user can synchronize the output phase across multiple LMX2594 devices. LMX2594 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. The software is simple with an intuitive and user friendly GUI. This EVM has complete circuit for synthesizer, optimized and tested for performance and includes a USB programming module.
  • 10MHz to 15GHz output frequency
  • Phase noise of -110dBc/Hz at 100KHz offset with 15GHz carrier
  • 45fs RMS jitter at 7.5GHz (100Hz to 100MHz)
  • Two differential outputs with programmable output power up to 7dBm at 15GHz
  • EVM has complete circuit for synthesizer optimized, tested for performance & USB programming module
