LMX1205 Evaluation Module

Description

The LMX1205 evaluation module (EVM) is designed to evaluate the performance of the LMX1205, which is a four-output, ultra-low additive jitter radio-frequency (RF) buffer, divider and multiplier. The device can buffer RF frequencies up to 12.8GHz, multiply RF outputs up to 12.8GHz, and divide outputs by up to 12.8GHz. This board consists of an LMX1205 device and an integrated USB2ANY programmer.

Features

  • 300MHz to 12.8GHz output frequency
  • 4 high-frequency clocks with corresponding SYSREF outputs
    • Shared divide by 2, 3, 4, 5, 6, 7 and 8
    • Shared multiply by 2, 3, 4, 5, 6, 7 and 8
  • Noiseless adjustable input delay up to 25ps with 1ps resolution
  • Individual adjustable output delays up to 10ps with 0.5ps resolution
  • 3.3V supply voltage (with onboard 2.5V LDOs) or 2.5V supply voltage (with LDOs bypassed)
  • –40ºC to +85ºC operating temperature
