HMC858 14 Gbps 2:1 Differential Selector SMT with Programmable Output Voltage

The HMC858LC4B is a 2:1 Selector designed to support data transmission rates of up to 14 Gbps, and selector port operation of up to 14 GHz. The selector routes one of the two single-ended inputs to the differential output upon assertion of the proper select port. The HMC858LC4B also features an output level control pin, VR, which allows for loss compensation or for signal level optimization.

All differential input signals to the HMC858LC4B are terminated with 50 Ohms to ground on-chip, and may be either AC or DC coupled. The outputs of the HMC858LC4B 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 HMC- 858LC4B operates from a single -3.3V DC supply and is available in a ceramic RoHS-compliant 4x4 mm SMT package.
