Welcome Here  Shenzhen Mingjiada Electronics Co., Ltd.

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 differential inputs to one or two desired outputs when the selected port is in position. The HMC857LC5 also incorporates an output level control pin, VR, which can be used for loss compensation or signal level optimisation.

All single-ended input signals of the HMC857LC5 are terminated at 50 Ω to on-chip ground and can be AC or DC coupled. The outputs of the HMC857LC5 can operate in differential or single-ended configurations. The outputs can be connected directly to a 50 Ω terminated system, or a galvanic isolation capacitor can be used if 50 Ω termination to an ungrounded DC voltage is used. 

The HMC857LC5 is supplied from a single -3.3V DC supply and is available in a RoHS compliant 5x5 mm SMT ceramic package.
