The HMC 703 has a 50 ohm reference path. Could you suggest alternatives to the SRSB348-50.000MHz that can drive the HMC 703 reference path? We cannot buy this part off mouser/digikey or other standard suppliers. Appreciate your input.
The Suntsu SRSB348-50.000MHz part will work fine even if its output is not specified for 50 ohm load. When the Suntsu 3.3V CMOS output is loaded with 50 ohm it meets the 0.6Vpp to 2.5Vpp HMC703 input requirement.
Most 3.3V oscillators with good phase noise and CMOS output will work. Look into options from Bliley (V105A), Crystek (CVHD-950), or Conner Winfield (CWX823).
