The HMC857LC5 is a 2x2 crosspoint switch designed to support data rates up to 14 Gbps and selector port operating frequencies up to 14 GHz. The selector routes the differential inputs to one or two desired outputs when the selected port is asserted. The HMC857LC5 also integrates an output level control pin, VR, for loss compensation or signal level optimization.
All single-ended input signals of the HMC857LC5 are terminated to on-chip ground at 50 Ω and can be AC or DC coupled. The output of the HMC857LC5 can be operated in differential or single-ended configurations. The output can be directly connected to a 50 Ω termination system, and DC blocking capacitors can be used if a 50 Ω terminated to a non-grounded DC voltage is used. The HMC857LC5 operates from a single -3.3V DC supply and is available in a RoHS-compliant 5x5 mm SMT ceramic package.
