14 Gbps 2 × 2 Crosspoint Switch with Programmable Output Voltage

The HMC857LC5 is a 2×2 Crosspoint Switch 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 HMC857LC5 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 HMC857LC5 are terminated with 50 Ohms to ground on-chip, and may be either AC or DC coupled. The outputs of the HMC857LC5 may be operated either differentially or single ended. Outputs can be connected directly to a 50 Ω terminated system, while DC blocking capacitors may be used if the terminating system is 50 Ohms to a non-ground DC voltage. The HMC857LC5 operates from a single -3.3V DC supply and is available in a ceramic RoHS compliant 5 × 5 mm SMT package.
