General Description
The HMC958LC5 is a 4:1 Selector designed to support data transmission rates of up to 14
Gbps and selector port operation up to 14 GHz. The selector routes the differential inputs to
either one or both of the desired outputs upon assertion of the appropriately selected port.
The HMC958LC5 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 HMC958LC5 are terminated with 50 Ohms to ground
on-chip, and may be either AC or DC coupled. The outputs of the HMC958LC5 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 HMC958LC5 operates from a single -3.3V DC
supply and is available in a ceramic RoHS compliant 5 x 5 mm SMT package.
