ASNT5051-KMC

Signal Switches, Multiplexers, Decoders Overview

The ASNT5051-KMC is a high-isolation broadband selector switch fabricated in SiGe technology. It routes one of two fully differential CML data inputs to a single differential output while blocking the other input. The device supports data rates up to 32 Gbps and features an analog bandwidth of 1.0 GHz for control inputs. It operates on a single +3.3V or -3.3V power supply with a typical power consumption of 287 mW. The IC includes internal 50 Ohm termination and provides a 550 mV single-ended output swing.

Signal Switches, Multiplexers, Decoders Procurement Notes

Verify the specific ordering suffix matches the required package type, as the KMC designation corresponds to the standard 24-pin CQFP package. Confirm that the application environment adheres to the recommended operating conditions for power supply voltage and junction temperature to ensure functional reliability. Check for RoHS compliance documentation if environmental regulations apply to the deployment.

Signal Switches, Multiplexers, Decoders Selection Notes

Select this component when a high-isolation, low-jitter selector switch is required for differential CML signals up to 32 Gbps. Ensure the design accommodates the specific power supply configuration, as PCB layouts differ significantly between positive and negative supply modes. Verify that the thermal management strategy addresses the heat dissipation requirements of the center heat slug on the CQFP package.
