The HMC858LC4B is a 2:1 Selector designed to

sup-port data transmission rates of up to 14 Gbps,

and selector port operation of up to 14 GHz. The

selector routes one of the two differential 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.
