LMX2595 EVM Instructions – 19-GHz Wideband Low Noise

PLL With Integrated VCO

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.

Changing Reference Oscillator and Setup

The reference can be single-ended or differential. To measure the performance of the PLL ONLY, the reference must have at least this level of performance. We understand that this can be a challenge at 100-Hz offset:

Table 4. Reference Oscillator Requirements

100-MHz REFERENCE MINIMUM REQUIREMENTS FOR A 0.4-dB IMPACT ON PLL INBAND PN

Offset [Hz] 100 1k 10k 100k

Noise level [

dBc/Hz]

(1)

A noise source 10 dB down from the PLL noise will contribute to raise the noise by 0.4 dB.

–139 –149 –159 –164

There are different options to provide a reference oscillator to LMX2595: Use on-board oscillator (default), Enable LMK61xx from Reference Pro PCB, use external oscillator.

By default the onboard oscillator is enabled. To use external reference, onboard oscillator must be disabled. Having multiple 100 MHz enabled or powered sharing VCCor Gnd will degrade the phase noise performance of LMX2595.

For differential pair connection:

1. Switch R24b to R24.

2. Switch R29b to R29

3. Must remove R33 to remove power from oscillator
