the difference between hmc703 and hmc704

the difference between hmc703 and hmc704?

  • The HMC704 PLL is used in wideband PLLVCO parts (HMC829, HMC830, HMC832, HMC833, HMC834 ).  Since these parts include a switched capacitor VCO the PLL die must include an autocal state machine to select the proper VCO band.  The HMC703 PLL design does not have this circuit. The HMC703 is mainly used as a stand alone PLL or integrated with a narrowband microwave VCO (HMC767, HMC768, HMC778).  The autocal state machine was replaced with sweeper functionality which allows more VCO modulation, ramping and phase control options.
