i need gerber files for HMC778 EVB.
Now,I want to use HMC767 and HMC778 to generate a X-band signal, A 50MHz TCXO is intended as a reference crystal. the ESPON's TG-5500CA is a clipped sinewave output, if it's suitable to choice for HMC767 and HMC778? or is there any other good choice…
I have the datasheet and operating guide documents as the following name. (from the web site)
Unfortunately, I don't have a HMC778 Evaluation Kit. I want to know how can program the HMC778 using…
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…
I am using HMC778 to generate single frequency output at 10.8 GHz. I am using SPI in HMC mode to program the device and the base XTAL frequency to HMC778 is 100 MHz. Can I get the register sequence and value for this configuration ??
Source code for the HMC778 is not available. Sorry.
Refer to HMC778 evaluation board, I have made a PLL board and its schematic is shown below. The RF output power of hmc778 should be 9dbm@10GHz. And I want to get 9-5+14=18dbm output power through a attenuation network and PA hmc441.
The problem is the…
hello, i would like your help in choosing a reference input clock for the HMC788 pll.
I am a student who use this pll for a project but i don't understand what reference clock to choose.
i know there are a lot of format for clocks and i am getting…
I have noticed that in the schematic of evolution board of HMC778, there is an option for pin "VCCVCO2". Shown as following.
I want to ask the function of "JP2" or is there any difference if I provided 5V to VCCVCO2 or not?…
I have a question about HMC778 from the customer.He wants to make the trigger at TRIG synchronize exactly with starting of frequency change.Then, do you have any timing specification between rising edge of TRIG and starting of frequency change?Is…
