Signal Switches, Multiplexers, Decoders Procurement Notes

Verify the specific package suffix 'PQC' corresponds to the standard 24-pin QFN configuration detailed in the datasheet. Confirm that the ordering information matches the manufacturer's current documentation, as suffixes may indicate variations in packaging or manufacturing origin. Ensure compatibility with the required thermal management practices for the center heat slug.

Signal Switches, Multiplexers, Decoders Selection Notes

Select this component when a high-isolation, broadband 1-of-2 switch is required for differential CML signals. It is suitable for applications demanding low jitter and minimal temperature variation over the industrial range. Consider the power supply configuration (positive vs. negative) early in the design phase, as PCB layout requirements differ significantly between the two modes.

Signal Switches, Multiplexers, Decoders FAQ

Can the ASNT5152-PQC operate with both positive and negative power supplies?

Yes, the device can operate with a negative supply (VEE = -3.3V, VCC = 0V) or a positive supply (VCC = +3.3V, VEE = 0V). Different PCB layouts are required for each configuration.

What is the maximum data rate supported by the switch?

The device supports a maximum data rate of 32 Gbps and has an analog bandwidth extending to 17 GHz.

How is the select signal controlled?

Selection is achieved through external DC biasing of the select signal inputs (CP/CN). An AC signal up to 1.0 GHz can also be applied to these inputs.
