DESCRIPTION
The temperature stable and broadband ASNT5052-PQC SiGe IC is a high isolation selector switch that is intended foruse in high-speed measurement / test equipment. ASNT5052-PQC can route one of its up to 28Gbps data inputs to its
output while effectively blocking the other data input with high isolation. Selection of a specific data input is achieved
through appropriate up to 1.0GHz external biasing of the selector signal inputs. The part’s I/Os support the CML logic
interface with on chip 50Ω termination and may be used differentially, AC/DC coupled, single-ended, or in any
combination. It operates from a single ±3.3V power supply.

POWER SUPPLY CONFIGURATIONThe ASNT5052-PQC can operate with either VCC = 0.0V and VEE = -3.3V or VCC = +3.3V and VEE = 0.0V.
Different PCB layouts will be needed for each different power supply combination.
All the characteristics detailed below assume VCC = 0.0V and VEE = -3.3V.

PACKAGE INFORMATIONThe chip die is housed in a standard 24-pin QFN package. The package’s mechanical information is available on thecompany’s website. It is recommended that the center heat slug located on the back side of the package be soldered toground to help dissipate heat generated by the chip during operation.
The part’s identification label is ASNT5052-PQC. The first 8 digits of the name before the underscore identify the baredie including general circuit family, fabrication technology, specific circuit type, and part version while the 3 digits
after the underscore represent the package’s manufacturer, type, and pin out count.
This device complies with the Restriction of Hazardous Substances (RoHS) per EU 2002/95/EC for all six substances.
