Part details & applications

The HMC678LC3C is a 2:1 Selector designed to support data transmission rates of up to 13 Gbps, and selector port operation of up to 13 GHz. The selector routes one of the two single-ended inputs to the differential output upon assertion of the proper select port. All single-ended input signals to the HMC678LC3C are terminated with 50 ohms to ground on-chip, and may be either AC or DC coupled.

The outputs of the HMC678LC3C may be operated either differentially or single-ended. Outputs can be connected directly to a 50 ohm terminated system, while DC blocking capacitors may be used if the terminating system is 50 ohms to a non-ground DC voltage. The HMC678LC3C operates from a single -3.3V dc supply and is available in a ceramic RoHS compliant 3x3 mm SMT package.
