Can I use a LVPECL source to drive the RF and/or the Ref input on a HMC4069.
I bought a HMC4069 evaluation board last month. It has 5 bit control pins which decide the frequency division ratio.
With A0-A4 1/0/0/0/0, it has to work with 1/2 ratio but failed. It doesn't work with 0/1/0/0/0, either. It works with A0-A4 1/1/1/0/0…
Closing this out due to lack of reply
Hi! I want to use an external VCO as the input of HMC4069(VCO), but i don't know how to design the circuit for the Vtune of the external VCO. How to get the Vutune needed loaded on the external VCO. Can anyone give some suggestions on this?Thanks a l…
Please can you confirm the availability of the Hittite HMC3716 and HMC4069 and can I have an up todate datasheet for both?
hmc4069 PD output : +/-5V (pin NU, ND)， charge pump current is 10mA;
suppose vco tuning voltage is 0~15V.
As you see, they are not equal , and the latter（15V） is higher than former（5V)
As the datasheet recommemded , the loop filer is one op circuits …
I would like to drive an ac-coupled differential 50 Ohm load with the ADCMP580 (or 582). The load is in fact the REF/NREF input of the HMC4069 (with DC block).
What is the best way to terminate the ADCMP580 outputs and to connect the REF/NREF input of…
