All differential inputs to the HMC725LC3C are CML and terminated on-chip with 50 Ohms to the positive supply, GND, and may be DC or AC coupled. The differential CMl outputs are source terminated to to 50 Ohms and may also be AC or DC coupled. Outputs can be connected directly to a 50 Ohm ground-terminated system or drive devices with CML logic input. The HMC725LC3C operates from a single -3.3 V supply and is available in ROHS-compliant 3x3 mm SMT package.
