What is Mcounter in HMC769? This block don`t shown in the HMC769 structure.

The Hitt-PLL tool can simulate phase noise at 9.1G and calculate jitter for the 10 KHz to 40 MHz integration limits. The HMC769 model files are included as part of the tool installation package. Set the output to 9.1G and change the Noise Integration…
I'm trying to use HMC769 as a FMCW signal generator. After 2 days' groping for the SPI interface, I have finally made HMC769 output fixed frequency in integer or fractional modes.
I followed the "PLLs WITH INTEGRATED VCO - MICROWAVE…
The HMC767, HMC769 and HMC778 share the same evaluation board. These can be found on the 'Discussion' section on the Full Product page for the HMC778 on the website (links back to EZ). I've attached…
The second capture better matches Figure 18 in the HMC769 Operating Guide but both should work.
Writing 0x09, 0x73, 0x70, 0x00 causes the device read register 0x10. Figure 18 in the HMC769 Operating Guide shows what to expect on LD/SDO with every subsequent…
I have a similar problem with HMC769. I'm using the original Hittite hmc769 evaluation board. I'm using external 20MHz xtal reference, and I'm sending registrers, using evaluation software (see attached registers file). I'm able to generate and…
We are new with HMC769LP6CE Fractional-N PLL with Integrated VCO SMT, 9.05 - 10.15 GHz and we are need to use this device for a single frequency 9GHz phase locked. As we are a microwave company we are bit thin on the knowledge of digital domain. We have…
