HMC748 Series

The HMC748 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. The HMC748 also features an output level control pin, VR, which allows for loss compensation or for signal level optimization.All single-ended input signals to the HMC748 are terminated with 50 ohms to VCCon-chip, and may be either AC or DC coupled. The outputs of the HMC748 may be operated either differentially or single-ended. Inputs or outputs can be connected directly to a 50 ohm to VCCterminated system, while DC blocking capacitors may be used if the terminating system is 50 ohms to ground. The HMC748 operates from a single +3.3V DC supply and is housed in a ceramic RoHS compliant 3x3 mm SMT package.APPLICATIONS2:1 Multiplexer up to 13 GbpsRF ATE ApplicationsBroadband Test & MeasurementSerial Data Transmission up to 13 GbpsRedundant Path SwitchingBuilt-in Test
