I’m looking for a PLL with VCO integrated having the following behaviors:
Band: 960MHz to 1220MHz
Frequency settling time plus writing time of the registers for changing frequency (time for changing frequancy): <30usec for a hopping distance equal at 63MHz
Spurious: 60dBc (better if it is 70dBc)
Step size: 10KHz
Frequency reference: 50MHz
I'd like to know if the HMC832 or the HMC830 can meet the above requarements.
Both HMC830 and HMC832 will meet these requirements but the application must utilize a tunable reference and manual tuning to meet the -60dBc spurious and hop time requirements. I've attached an appnote on manual tuning. With a fixed 50MHz reference Figure 21 in the HMC830 datasheet shows at frequencies close to 2GHz VCO frequency (1000MHz output) IBS spurs for some channels near the integer boundary could reach -50dBc. With tunable reference the spur levels drop below -100dBc.
Phase noise simulations at 1MHz offset for both parts (1220MHz output) is around -144dBc/Hz using the HMC830 default eval board loop filter.
