The temperature stable and broadband ASNT5152-PQC SiGe IC is a high isolation selector switch that is intended for use in high-speed measurement / test equipment. ASNT5152-PQC can route one of its differential data input signals d0p/d0n or d1p/d1n to its differential output outp/outn while effectively blocking the other data input with high isolation. Selection of a specific data input is achieved through appropriate external DC biasing of the select signal inputs cp/cn. It is also possible to apply an up to 1GHz AC signal to the select 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. In the DC-coupling mode, the input signal’s common-mode voltage should comply with the specifications shown within the electrical characteristics section within the part’s datasheet. In the AC-coupling mode, the input termination provides the required common-mode voltage automatically. The differential DC signaling mode is recommended for optimal performance.
