asking about HMC769 regidter files.

[stepannp]

Hi everybody,

I want to control VCO-PLL (HMC769) with my board by using atmega32A. However, I have some problems.

1. My HMC769 always runs in 8.4 GHz or 10.0 GHz, even I use 2 register maps from hittite.(HMC769_register_fraction.txt, HMC769_register_integer.txt). Anybody can tell me these files are correct? If not please send me these files.

2. How can I count Nint and Nfrac (Fvco = 9.3GHz, fxtal = 48MHz)?

Thank you very much.

PS: HMC769_register_fraction.txt
