The PMCC_VCO20G /24G /25G /26G /30G is a set of fully differential high speed VCOs covering 20GHz … 30GHz frequency range, designed using Jazz SiGe120 (SBC18HX) process. Differential architecture ensures substrate and power supply noise immunity. Macro features optional 50 Ohm terminated buffers at its output. Built-in power-down mode enables power saving in case when block is not operated. Operation frequencies, I/O signal levels, control functions and features can be customized upon special agreement.
